Dežru Spec-RS
Dežru Spec-RS Coilover Suspension
Street During the Week. Track on the Weekend.
The Spec-RS was built for a very specific driver.
The one who spends all week driving to work, then spends the weekend chasing apexes.
The one who drives hundreds of miles to a track day, beats on the car all weekend, then drives it home without needing a trailer.
The one who wants a suspension capable of serious performance but refuses to live with a miserable daily driving experience.
If that sounds familiar, the Spec-RS was built for you.
At its core, the Spec-RS bridges the gap between a street suspension and a motorsport suspension. It offers significantly more capability than the typical street-focused coilover while remaining comfortable enough to enjoy every day.
Because the best performance car is the one you actually want to drive.
Why We Built It
As enthusiasts ourselves, we've always felt there was a gap in the market.
Many street coilovers perform well until the pace increases.
Many track-focused systems perform brilliantly on track but become exhausting everywhere else.
The Spec-RS was developed to live comfortably in both worlds.
Using inverted dampers, external reservoirs, Bilstein COB digressive pistons, and externally adjustable rebound control, the Spec-RS gives drivers the ability to tune the suspension around their driving style and environment.
Comfortable for the commute.
Capable at the limit.
Ready for whatever comes next.
What You'll Notice First
The first thing you'll notice is confidence.
The car feels more composed under braking, more stable during rapid transitions, and more predictable when approaching the limit of grip.
The external reservoir design provides additional oil volume and improved heat management, helping the suspension maintain consistent performance during aggressive driving sessions.
When the road gets rough or the pace increases, the Spec-RS simply feels at home.
- Exceptional body control
- Improved high-speed stability
- Greater consistency during aggressive driving
- Reduced brake dive and acceleration squat
- Improved cornering confidence
- Street comfort with track capability
Adjustment That Actually Matters
The Spec-RS features externally adjustable rebound damping, allowing drivers to quickly tailor the suspension to their needs.
Heading to work?
Soften the settings.
Heading to autocross?
Add control and responsiveness.
Track day this weekend?
Dial in the suspension to suit the circuit and your driving style.
The goal isn't endless adjustment for the sake of adjustment.
The goal is giving enthusiasts useful control over how their car feels and performs.
Built for Drivers Who Push Their Cars
The Spec-RS was designed for enthusiasts who regularly ask more from their cars.
Drivers who enjoy canyon roads.
Drivers who attend autocross events.
Drivers who participate in HPDE programs and track days.
Drivers who care about lap times but still want to enjoy the drive home afterward.
This suspension was built for people who use performance, not just talk about it.
Premium Components Throughout
Every component in the Spec-RS exists for a reason.
- Inverted damper architecture
- External reservoir design
- Bilstein COB digressive piston technology
- 1-way rebound adjustment
- Hyperco spring packages
- Vehicle-specific valving and spring recommendations
- Assembled and supported in the USA
The result is a suspension capable of handling far more abuse than the average enthusiast will ever throw at it.
Who Is Spec-RS For?
- Frequent autocross competitors
- HPDE and track day enthusiasts
- Aggressive canyon road drivers
- Performance-focused daily drivers
- Enthusiasts seeking one suspension for everything
Who Should Consider Something Else?
Choosing the right suspension matters.
- If your primary goal is value and daily driving, consider the Spec-A.
- If you want the ultimate balance of comfort and performance, consider the Spec-S.
- If you're building a dedicated competition vehicle and demand maximum adjustability, consider the Spec-R.
The Spec-RS exists for drivers who genuinely want both worlds.
The Bottom Line
The Spec-RS is for enthusiasts who refuse to choose between street and track.
It delivers the comfort needed for daily driving, the durability needed for repeated track use, and the adjustability needed to fine-tune the car around your goals.
One car.
One suspension.
Street all week. Track all weekend.
