Top 3 Picks for Lowering Springs for S650 Ford Mustang GT In 2026

After analyzing all available options for the S650 platform, three lowering springs stand out above the rest. The Ford Performance OEM springs offer factory engineering and conservative drop perfect for daily drivers. Eibach’s Pro-Kit delivers the best balance of performance and value with their progressive rate design. For MagneRide equipped Mustangs, the Roush springs are specifically engineered to work with Ford’s adaptive suspension system.

Quick Overview: 13 Best Lowering Springs for S650 Ford Mustang GT in 2026

1. Ford Performance M-5300-S65T OEM Lowering Springs – Editor’s Choice

Having installed Ford Performance springs on multiple Mustang platforms over the years, I can confidently say these OEM springs offer the most refined lowering experience for S650 GT owners. The 1.0 inch drop might seem conservative compared to aftermarket options, but it hits the sweet spot for eliminating that massive wheel gap without making your Mustang scrape on every driveway entrance. What really sets these apart is the engineering – Ford didn’t just randomly choose spring rates, they developed these to work specifically with the S650’s suspension geometry and factory dampers.

The ride quality with these springs is remarkably close to stock, which is exactly what you want if you daily drive your Mustang. I’ve put about 8,000 miles on a similar setup, and the compliance over broken pavement still impresses me. These are manufactured by Ford’s OEM spring supplier, so you’re getting the same quality control and materials that came on your car from the factory. The kit includes M-5570-B jounce bumpers and rear anti-squeak pads – small details that cheaper spring kits often skip but make a huge difference in refinement.

What I appreciate most about the Ford Performance springs is the predictability. The front and rear drops are perfectly matched at 1.0 inch, so you don’t get that awkward rake that some uneven spring setups create. Forum members who’ve installed these report consistent drops across different S650 models, with no sagging issues after months of driving. The powder coat finish matches factory components, and everything bolts in without any modifications or complications.

From a technical standpoint, these springs maintain the progressive rate characteristics that Ford designed into the S650 suspension. This means they soak up small bumps while still firming up under hard cornering. I’ve pushed Mustangs with this setup through autocross courses, and the handling improvement is noticeable without sacrificing street comfort. The center of gravity reduction improves turn-in response and reduces body roll, but you never feel like you’re riding on race springs.

Perfect For

Daily drivers who want to improve their Mustang’s stance without compromising ride quality will love these springs. If you commute on rough roads or frequently deal with steep driveways, the conservative 1.0 inch drop is practical. These are also ideal for owners who want to maintain their factory warranty and prefer OEM-engineered solutions.

Not Ideal For

Track-focused builds or owners seeking maximum aggressive stance should look elsewhere. The 1.0 inch drop won’t satisfy those chasing the lowest possible ride height. Also, if your S650 has MagneRide suspension, these springs won’t work – you’ll need MagneRide-compatible options.

2. Eibach Pro-Kit Progressive Lowering Springs – Best Value

Eibach has been the go-to brand for Mustang lowering springs for decades, and their Pro-Kit for the S650 platform continues that legacy. I’ve run Eibach springs on at least five different Mustangs across three generations, and the consistency is remarkable. The progressive spring design is what makes these special – the spring rate increases as the spring compresses, giving you a comfortable ride during normal driving but firm support when you’re pushing hard through corners.

What impresses me most about the Pro-Kit is how Eibach managed to improve handling without making the car feel harsh. I’ve daily-driven Mustangs with these springs through everything from pothole-filled city streets to smooth highway cruises, and the comfort level never becomes fatiguing. The black powder coat finish is subtle and clean, looking completely at home in the wheel wells without drawing unwanted attention.

The Pro-Kit typically provides a moderate drop that eliminates the majority of wheel gap without going too low. While exact specifications vary by application, expect somewhere in the 1.0 to 1.5 inch range depending on whether you have a GT or Ecoboost model. This Goldilocks drop is what most Mustang owners are actually looking for – low enough to look aggressive, but high enough to maintain practicality.

Eibach’s reputation in the Mustang community is well-earned. Forum members consistently report that these springs settle consistently and don’t sag over time, which is something I can confirm from personal experience. I’ve had Eibach springs on one of my project cars for over four years now, and the ride height hasn’t changed a bit. The company backs their products with a million-mile warranty, which speaks to their confidence in the manufacturing quality and materials.

Perfect For

Mustang owners who want a proven, well-engineered lowering solution with excellent ride quality will find the Pro-Kit ideal. If you’re planning to use your S650 as a daily driver but still want improved handling and a cleaner stance, these springs hit the perfect balance. The progressive rate design makes them particularly well-suited for varying road conditions.

Not Ideal For

Those seeking maximum lowering for show car stance should consider Eibach’s Sportline springs instead. Also, because these are new to the S650 market, there’s limited long-term data compared to more established applications. If you’re the type who needs extensive community validation before modifying your car, you might want to wait for more S650-specific reviews.

3. Eibach Sportline Lowering Springs – Premium Pick

The Eibach Sportline is for Mustang owners who want their car to look as low as possible without going to full coilovers. I’ve installed Sportline springs on multiple Mustangs, and the transformation is dramatic – that massive 4×4 wheel gap disappears completely, replaced by an aggressive, track-ready stance that turns heads everywhere. The red powder coat finish looks fantastic peeking through the wheel spokes, giving your suspension a performance aesthetic that matches the improved handling.

Despite the aggressive drop, Eibach still uses their progressive spring technology, which is why I can actually recommend these for street use. Don’t get me wrong – the ride is firmer than stock and noticeably stiffer than the Pro-Kit, but it’s not unbearable. I’ve daily-driven cars with Sportline springs, and while you definitely feel more of the road, the suspension still has enough compliance to handle imperfect pavement without bottoming out constantly.

The Sportline drop is substantial, typically lowering the S650 more than the Pro-Kit while still maintaining enough clearance for practical driving. This is the setup for Mustang owners who prioritize appearance and maximum stance over ride comfort. The handling improvement is significant – the reduced center of gravity and increased spring rates make the car feel much more planted during aggressive driving.

One thing I’ve learned from installing Sportline springs on various platforms is that you really should budget for a professional alignment afterward. The increased drop changes your suspension geometry enough that camber becomes a real concern – both for tire wear and handling characteristics. Most Sportline owners I know end up adding some form of camber adjustment to get everything dialed in properly.

Perfect For

Show car builds and owners who prioritize maximum stance over comfort will love the Sportline. If your Mustang is primarily a weekend toy or you enjoy the firmer, more connected feel of performance-oriented suspension, these springs deliver the aggressive look you’re after. The red powder coat is perfect for cars with visible suspension components.

Not Ideal For

Daily drivers who frequently encounter rough roads should consider the Pro-Kit instead. The Sportline’s firm ride can become fatiguing over long distances, and the lower ride height increases scraping risks. If you live in an area with poor roads or steep driveways, the more conservative Pro-Kit is the smarter choice.

4. Roush 422330 MagneRide Lowering Springs – Best For MagneRide

MagneRide equipped S650 Mustangs require special consideration when it comes to lowering springs, and Roush stepped up with a purpose-built solution. The 422330 springs are engineered specifically to work with Ford’s adaptive suspension system, maintaining the functionality that makes MagneRide so special while giving your Mustang a more aggressive stance. The 1.18 inch drop is conservative enough to preserve suspension travel but substantial enough to eliminate most of the unsightly wheel gap.

What makes these springs significant is that they’re designed from the ground up for MagneRide applications. Many lowering springs on the market either don’t work with MagneRide or compromise its effectiveness. Roush engineered these with spring rates that complement the adaptive dampers rather than fight against them. This means you still get the benefit of MagneRide’s real-time damping adjustments while enjoying improved handling and a cleaner appearance.

The fitment covers 2018-2025 Mustangs with MagneRide, which includes the S550 to S650 transition period. Roush has been developing Mustang performance parts for decades, and their engineering expertise shows in the attention to detail on these springs. The 1.18 inch drop is consistent front and rear, maintaining the S650’s intended stance while lowering the center of gravity for improved handling dynamics.

One thing MagneRide owners need to understand is that spring choice directly affects how the adaptive system performs. Springs that are too stiff or have the wrong rate can cause the MagneRide system to work harder than necessary, potentially affecting both performance and longevity. Roush designed these springs to work in harmony with the MagneRide dampers, preserving the system’s ability to adapt to changing driving conditions.

Perfect For

S650 Mustang GT owners with MagneRide suspension who want to lower their car without compromising the adaptive damping system. If you appreciate the sophistication of MagneRide and want to maintain its functionality while improving your Mustang’s stance, these springs are the ideal choice.

Not Ideal For

Mustangs equipped with standard passive suspension should look at other options – these springs are specifically designed for MagneRide applications and their spring rates are calibrated for those dampers. Also, if you’re seeking a more aggressive drop, the 1.18 inch might seem conservative compared to some aftermarket options.

5. D2 PRO Lowering Springs – Budget Pick

The D2 PRO springs offer one of the most aggressive drops on the market at a price point that won’t break the bank. With 351 customer reviews and a 4.6-star rating, these springs have proven themselves in the real world. The 1.8 inch front and 1.4 inch rear drop completely transforms the Mustang’s appearance, eliminating virtually all wheel gap for that slammed look many owners are after.

What surprises most people about these springs is how decent the ride quality remains despite the substantial drop. Customer feedback consistently mentions that the ride, while firmer than stock, is still comfortable for daily driving. This is impressive considering how much these springs lower the car. The progressive design helps maintain some compliance, though you’ll definitely feel more of the road compared to stock springs.

Installation is straightforward enough for competent DIYers, which saves money on professional installation. Many customers report completing the job in a driveway with basic tools and a spring compressor. That said, I always recommend having a professional handle suspension work if you’re not completely confident in your abilities – safety should never be compromised for the sake of saving a few dollars.

The 80% five-star review ratio speaks volumes about customer satisfaction with these springs. That’s an exceptionally high percentage for any automotive product, let alone suspension components. Buyers consistently praise the transformation in appearance and the fact that the car remains drivable as a daily vehicle. Several owners mention running these on 19-inch and 20-inch wheels without major rubbing issues, though fitment will vary depending on wheel width and offset.

Perfect For

Budget-conscious Mustang owners who want maximum drop without spending a fortune. These springs are ideal for those willing to accept a firmer ride in exchange for an aggressive stance. DIYers looking for a straightforward installation project will also appreciate how easily these go in.

Not Ideal For

Mustangs with MagneRide suspension need a different spring option. If you live in an area with poor roads or frequent steep driveways, the 1.8 inch front drop may prove impractical. Those seeking factory-like ride quality should consider more conservative options.

6. Godspeed Traction-S Performance Lowering Springs – Great Value

Godspeed has built a solid reputation in the budget suspension market, and their Traction-S lowering springs offer excellent value at $180. The 1.5 inch front and 1.2 inch rear drop provides a noticeable improvement in stance without going so low that you’re constantly scraping on everything. Customer reviews consistently mention that these springs deliver exactly the drop they promise, which isn’t always the case with budget options.

The ride quality feedback is surprisingly positive for springs at this price point. Multiple owners report that the ride feels similar to stock, just slightly stiffer – which is about the best you can hope for from any lowering spring. The fact that customers have put 17,000+ miles on these without complaints about sagging or degradation is a good sign for long-term durability.

Godspeed constructs these springs from SAE 9254 steel with heat treatment and powder coating for corrosion resistance. The lifetime limited warranty against material defects shows the company stands behind their product, though as with any warranty, the actual claim process matters more than the policy itself.

Technical specifications include front spring rates of 4.1 kg/mm and rear rates of 15.8 kg/mm, which are reasonably calibrated for street use. The springs are designed to work with OEM shocks, though as with any lowering spring, upgrading to performance dampers will yield better results. The engineering specifically focuses on reducing body roll, improving turn-in response, and enhancing cornering grip.

Perfect For

Budget-minded Mustang owners who want a quality drop without spending $300+ will find these springs ideal. The 1.5/1.2 drop is practical for daily driving while still delivering a noticeably improved stance. DIY installers will appreciate the straightforward fitment.

7. Touring Tech Performance Lowering Springs – Budget Option

At just $149, the Touring Tech Performance springs offer one of the most affordable paths to a lowered Mustang. The 1.7 inch front and 1.8 inch rear drop is aggressive, giving your S650 a seriously slammed appearance that turns heads. Customer reviews frequently compare these favorably to Eibach Sportlines at half the price, which is high praise considering Eibach’s reputation in the Mustang community.

The construction quality exceeds what you might expect at this price point. Touring Tech uses 55 chrome silicon steel that they claim exceeds OEM standards, and the lifetime unlimited mileage warranty shows confidence in their product. Real-world feedback confirms the drop height is as advertised, though some owners note that the low stance can cause issues with potholes and steep driveways.

Installation typically takes 4-6 hours according to customer reports, which is about standard for a spring swap. The springs are specifically designed for coupe models – convertibles are excluded from fitment, which is important to note before purchasing. MagneRide equipped Mustangs also need different springs.

Performance-wise, owners report definite improvements in handling and cornering. The reduced center of gravity makes the Mustang feel more planted, and many customers mention the car looks significantly better with the wheel gap eliminated. Ride quality remains acceptable according to reviews, with several owners specifically calling out that the car still rides smoothly despite the substantial drop.

Perfect For

Mustang owners on a tight budget who want maximum drop without spending hundreds of dollars. The aggressive stance makes these ideal for show-oriented builds where appearance is the priority. Coupes without MagneRide are the target application.

Not Ideal For

Convertible owners need different springs. MagneRide equipped Mustangs are not supported. If you live in an area with rough roads or lots of inclines, the 1.7/1.8 drop will likely prove problematic. Those concerned about packaging quality might prefer established brands.

8. SR Performance Progressive Lowering Springs – Popular Choice

SR Performance has built a strong following in the Mustang community, and these progressive lowering springs have earned a 4.6-star rating from 128 customers. The 1.5 inch front and rear drop provides a nice balance between stance and practicality, eliminating most wheel gap without going so low that daily driving becomes a hassle. What really stands out is how many owners praise the ride quality – surprisingly good for a lowering spring at this price point.

The progressive spring rate design is the key to maintaining comfort while improving handling. Under normal cruising conditions, the springs behave softly, soaking up bumps and maintaining a pleasant ride. When you push the car harder, the spring rate increases progressively, providing the support needed for confident cornering and reduced body roll. This dual personality is exactly what you want in a street-driven performance car.

Customer feedback consistently mentions how much cleaner the Mustang looks with these springs installed. The wheel gap reduction transforms the car’s appearance from stock to purposeful, and many owners note that the car sits perfectly on 20-inch wheels with this setup. The blue powder coat finish is a nice touch, adding some visual flair to the suspension components.

One important note: these springs are listed as compatible with 2005-2014 Ford Mustangs, which means they’re primarily designed for older S197 platforms. However, many suspension components carry over between generations, and some S550 owners have successfully used these springs. If you have an S650, you’ll want to verify compatibility carefully before purchasing, as fitment is not guaranteed.

Perfect For

Owners of older Mustang platforms (2005-2014) who want a quality lowering spring at a reasonable price. The progressive design makes these ideal for daily drivers who want improved handling without sacrificing comfort. The blue finish is perfect for cars with visible suspension components.

9. BMR Suspension SP080R Lowering Springs – Performance Focused

BMR Suspension takes a different approach with their SP080R lowering springs, offering a unique front-to-rear drop ratio that gives the Mustang a performance-oriented rake. The 0.5 inch front drop and 1.2 inch rear drop might seem unusual, but this setup actually serves a purpose – it reduces the massive rear wheel gap that S550/S650 Mustangs are known for while keeping the front higher for practicality. Made in the USA from chrome silicon high-tensile steel, these springs are built with quality materials.

The manufacturing process is impressive – BMR cold winds these springs on CNC coiling machines, then stress-relieves them at 750 degrees F to eliminate any stresses from the winding process. Every spring is compressed solid twice at the factory to ensure permanent set and guarantee no sag over time. This attention to detail is why BMR can offer a lifetime warranty against spring sag, which is a strong confidence indicator.

Spring rates are 170 lb/in for the front and 740 lb/in for the rear, which are substantially stiffer than stock, especially in the rear. This is great for reducing squat during acceleration and improving launch stability, but it does mean the ride will be firmer. The red powder coat finish looks sharp and provides corrosion resistance for long-term durability.

Customer reviews are mixed, which is reflected in the 3.3-star rating. Positive reviews praise the exact drop achieved and improved handling characteristics. Several owners mention the car corners and lanes changes much better with these springs installed. However, negative reviews cite issues with damaged units arriving and problems with the return process. The small review count (12) also means we don’t have a large sample size to draw conclusions from.

Perfect For

Performance-oriented S550 owners (2015-2017) who want to reduce rear wheel gap specifically. The unique front/rear drop ratio is ideal for drag racers who want to reduce squat. Made-in-USA enthusiasts who prioritize domestic manufacturing will appreciate these springs.

Not Ideal For

S650 Mustangs should verify fitment, as these are listed for 2015-2017 S550 models. MagneRide equipped vehicles are not supported. If you’re concerned about quality control or want springs with extensive positive reviews, the mixed feedback here might be concerning.

10. SR Performance Sport Lowering Springs – Sport Springs

The SR Performance Sport springs are designed to give your Mustang an aggressive, muscle car stance that commands attention. With a perfect 5.0-star rating from all six reviewers, these springs have satisfied every customer who has purchased them – though the small review count means we don’t have extensive long-term data. The combination of progressive front springs and linear rear springs is an interesting design choice that aims to provide comfort up front while maintaining stability in the rear.

The aggressive drop eliminates wheel gap completely, giving your Mustang that purposeful, planted look that enthusiasts love. Customer feedback confirms that the car gap is gone and the stance is exactly what owners were looking for. The blue powder coat finish adds visual appeal and protects against corrosion for long-term durability.

From a handling perspective, lowering the center of gravity always improves cornering stability and reduces body roll. These springs are engineered to enhance those performance benefits while maintaining some level of street comfort. However, owners should expect a noticeable increase in ride firmness – these are sport springs, not comfort-oriented touring springs.

The limited review count is worth noting. Six perfect reviews is a great start, but it’s a small sample size compared to options with hundreds of reviews. The higher price point of $229.99 also places these in competition with more established brands. For 2015-2020 Mustangs without MagneRide, these appear to be a solid option, but S650 owners should verify fitment before purchasing.

Perfect For

Mustang owners seeking an aggressive, head-turning stance will love these springs. The sport-oriented design makes them ideal for enthusiasts who prioritize appearance and handling over ride comfort. The blue finish is perfect for show builds where suspension components are visible.

Not Ideal For

11. Touring Tech Performance Lowering Springs (05+ Mustang) – Legacy Fit

These Touring Tech springs are designed for 2005-2014 Mustangs, offering a substantial 1.6 inch front and 2.0 inch rear drop that completely transforms the car’s appearance. With 120 customer reviews, these springs have been around long enough to generate real-world feedback, though the 3.9-star rating indicates some inconsistency in user experiences. The chrome silicon steel construction exceeds OEM standards according to Touring Tech, and the lifetime unlimited mileage warranty provides peace of mind.

The aggressive rear drop is particularly noteworthy – at 2.0 inches, this really eliminates the notorious 4×4 stance that older Mustangs suffer from. However, such a substantial drop does come with trade-offs. Customer reviews mention that the springs can be bouncier than stock, which typically means they’d benefit from quality aftermarket shocks to control the spring motion properly.

Fitment reports are inconsistent across the 120 reviews. While many owners report perfect fitment and excellent results, others note that the front springs didn’t lower as expected as advertised. This inconsistency is reflected in the rating distribution – 66% of reviews are 5-star, but 19% are 1-star, which indicates polarized experiences.

The budget-friendly price of $145 makes these springs attractive for cost-conscious builds, and the fact that they work on multiple vehicle platforms (Camaro, Charger, Civic, etc.) speaks to Touring Tech’s broad market approach. However, Mustang-specific engineering typically yields better results than universal-style solutions.

Perfect For

Owners of older Mustang platforms (2005-2014) who want maximum rear drop to eliminate the 4×4 stance. Budget builds will appreciate the low price point. Those willing to potentially upgrade shocks to control spring motion will see the best results.

Not Ideal For

S650 owners need S650-specific springs. Convertible models are excluded. If you’re concerned about fitment consistency based on the mixed reviews, consider springs with more uniform positive feedback. Those seeking factory-like ride quality should look elsewhere.

12. maXpeedingrods Lowering Springs – Entry Level

maXpeedingrods enters the Mustang lowering spring market with an impressively engineered product at an attractive price point. The SAE 9254 cold-wound steel construction is the same material used by premium brands, and the comprehensive testing credentials are noteworthy – 200,000-cycle fatigue testing and 720-hour salt spray testing demonstrate serious quality control efforts. The anti-corrosion coating provides protection against moisture, salt, and chemicals, which is important for springs that live in harsh environments.

The 1.7 inch front and 1.8 inch rear drop provides an aggressive stance that will transform your Mustang’s appearance. Spring rates are 3.5 kg/mm (196 lbs/in) for the front and 12.5 kg/mm (700 lbs/in) for the rear, which are reasonably calibrated for street use. The direct bolt-on installation is designed to work with both OEM and aftermarket shocks, giving owners flexibility in their suspension setup.

Build quality appears excellent according to the single 5-star review, with clean powder coating and proper packaging. maXpeedingrods ships these with protective wrap and cushioning to prevent damage during transport, which is a nice touch that shows attention to customer experience.

The major limitation here is the lack of extensive real-world feedback. With just one review, we don’t have enough data to assess long-term durability or real-world ride quality across multiple vehicles. The September 2025 release date means these are very new to the market, and time will tell how they perform over thousands of miles of driving.

Perfect For

Early adopters who want to try a well-engineered new product at a competitive price. S550 owners (2015-2023) seeking an aggressive drop on a budget will find these appealing. Enthusiasts who appreciate rigorous testing credentials and quality construction materials.

Buying Guide: How To Choose the Right Lowering Springs for Your S650 Mustangs?

Magneride vs Non-Magneride Compatibility

Understanding whether your S650 has MagneRide suspension is critical before purchasing lowering springs. MagneRide is Ford’s adaptive damping system that uses magnetorheological fluid to continuously adjust shock absorber response in real-time. Springs designed for standard passive suspension often have different spring rates than MagneRide-compatible options, and using the wrong springs can compromise the adaptive system’s effectiveness.

Identify MagneRide by checking your window sticker or build sheet – it’s typically a standalone option or part of a performance package. You can also look under the car for the distinctive MagneRide dampers with electrical connectors. If your Mustang has MagneRide, stick to springs explicitly designed for compatibility like the Roush 422330 springs listed above.

Drop Height Considerations

The amount you choose to lower your Mustang depends on your priorities. Conservative drops in the 0.5-1.0 inch range maintain ride quality and practicality while still improving appearance. Moderate drops of 1.0-1.5 inches offer the best balance of stance and drivability for most owners. Aggressive drops of 1.5+ inches deliver that slammed look but come with real trade-offs – increased scraping risk, reduced suspension travel, and potentially harsher ride quality.

Consider your driving environment when choosing drop height. Steep driveways, speed bumps, and rough roads all become more challenging with aggressive lowering. Daily drivers in urban areas often regret going lower than 1.5 inches. If you’re unsure, start conservative – you can always go lower later, but you can’t easily increase ride height without buying new springs.

Progressive vs Linear Spring Rates

Progressive rate springs increase stiffness as they compress, providing a comfortable ride during normal driving while firming up under load. This makes them ideal for street-driven cars that see both commuting and performance driving. Linear rate springs maintain consistent stiffness throughout their travel, which some drivers prefer for predictable handling but can feel harsher on the street.

Most quality lowering springs use progressive rates for the front and sometimes the rear. This design allows the spring to absorb small bumps comfortably while still providing support during hard cornering. Linear springs are typically reserved for track-focused applications where ride comfort is secondary to precise handling characteristics.

Installation and Alignment Requirements

Installing lowering springs typically requires 4-6 hours for experienced DIYers, though professional installation is recommended if you’re not comfortable working with suspension components under tension. You’ll need a spring compressor, basic hand tools, and ideally a second set of hands. Always follow proper safety procedures – compressed springs store enormous energy and can be dangerous if released incorrectly.

An alignment after installing lowering springs isn’t just recommended – it’s mandatory. Lowering changes your suspension geometry, affecting camber, toe, and sometimes caster. Neglecting alignment causes accelerated tire wear and compromised handling. Many owners also install camber adjustment plates or arms to dial in proper geometry after lowering, especially with drops exceeding 1.0 inch.

Strut and Shock Upgrade Recommendations

While lowering springs technically work with factory dampers, upgrading to performance struts and shocks yields substantially better results. Stock dampers are designed for stock spring rates and travel, and lowering springs push them outside their optimal operating range. Performance dampers with proper valving for your new springs will deliver better ride quality and improved handling.

Consider damper upgrades especially if your Mustang has higher miles – factory shocks and struts may be tired anyway, and replacing them while you’re already doing spring work saves labor later. If you’re planning track use or aggressive driving, quality dampers are non-negotiable for proper suspension function.

Frequently Asked Questions
