Coilovers: The Suspension Secret Behind Drifting, Racing, and Street Performance
When it comes to maximizing performance on the street or the track, few upgrades make a bigger difference than a properly designed coilover suspension system. Whether you're drifting through tight corners, pushing lap records in a time attack, or simply dialing in your daily driver's handling, coilovers provide unmatched adjustability, stability, and control.
In the world of motorsports and performance driving, SLR (Street Legal Racing) products have become synonymous with high-quality, precision-engineered suspension components. Their coilovers, born from the real-world demands of drifting and competitive racing, are a prime example of how purpose-built parts can transform a car’s capabilities.
What Are Coilovers?
A coilover is a combination of a shock absorber (damper) and a coil spring wrapped around it. Unlike traditional shock and spring setups, coilovers offer height adjustability, often along with damping adjustment (compression and rebound). This allows drivers to tailor their suspension for different surfaces, driving styles, and performance goals.
There are two main types:
Sleeve-style coilovers, which use adjustable sleeves on factory struts.
Full-body coilovers, which are entirely self-contained units, designed for true performance applications.
SLR focuses on the latter, building full-body coilovers machined in the USA from premium materials to meet the demands of motorsport.
Coilovers for Drifting
Drifting is one of the most demanding motorsport disciplines in terms of suspension geometry and control. Drivers must maintain control at extreme slip angles while transitioning rapidly between directions. This puts enormous stress on suspension components and demands fine-tuned handling characteristics.
SLR coilovers are designed with:
High-quality dampers to manage rapid weight shifts
Custom spring rates to handle aggressive drift entries and exits
Adjustable ride height and camber plates for dialing in front-end grip and steering response
But more importantly, SLR designs every component with drift-specific geometry in mind. What started as a need to improve BMW drift setups in the mid-2000s has grown into a lineup of parts that support drivers across the globe. SLR’s drift coilovers allow for full lock without binding or reverse Ackerman issues, enabling smoother transitions and better tire wear.
Coilovers in Circuit Racing & Time Attack
In grip racing, precision and consistency are key. Coilovers need to maintain consistent tire contact and manage body roll without sacrificing ride quality. For time attack, where milliseconds matter, suspension tuning becomes an art form.
SLR’s coilovers are track-tested, with proven results:
Class wins and lap records at various tracks around the world
Multi-level damping adjustment to fine-tune rebound and compression
Solid mounts and spherical bushings for maximum chassis feedback
The result? Suspension that doesn’t just survive a race weekend—it wins it. Whether you're tackling Sebring’s bumps or carving through smooth alpine roads, SLR coilovers offer the balance of compliance and stiffness needed for confidence and speed.
Street Performance with Track DNA
What sets SLR apart is their commitment to building parts that perform on track but are livable on the street. While many high-performance coilovers sacrifice comfort for stiffness, SLR’s experience across multiple racing disciplines ensures that their street offerings strike the perfect balance.

Drivers using SLR coilovers on the street benefit from:
Custom valving that offers performance without punishing ride harshness
Height adjustability to suit aesthetics or function (like wheel clearance or daily drivability)
Anodized and plated components that resist corrosion for long-term reliability
These features make SLR coilovers ideal for daily-driven performance cars—providing improved cornering, sharper steering response, and better control in emergency situations, all while maintaining a compliant ride.
Built by Racers, For Racers
SLR’s story is rooted in necessity. Back in 2006, when no one made drift parts for BMWs, SLR’s founder started fabricating his own—beginning with custom knuckles and eventually moving into complete suspension systems. By 2009, his “side project” was outperforming his day job, and SLR was born.
Fast forward to today, and SLR still builds its coilovers and suspension components in the USA, using locally sourced materials. Every major part is CNC-machined, anodized, plated, and rigorously tested to meet the demands of real-world motorsports.
SLR's no-compromise approach means you're getting parts built with intention—not mass-produced with shortcuts. And unlike some brands, SLR avoids the inflated “BMW-tax,” making pro-level performance accessible without sacrificing quality.
Conclusion: Coilovers That Do It All
From the smoky corners of a drift track to the apex of a high-speed racing circuit, and even your local backroads—coilovers are the backbone of a performance vehicle. When engineered correctly, like those from SLR, they deliver control, adjustability, and confidence for every kind of driver.
So whether you're chasing podiums or just want your daily to feel dialed in, SLR coilovers are ready for the ride.
Precision-built. Purpose-driven. Performance-proven. That’s the SLR standard.
