Built for razor-sharp response and legendary lightweight performance.
Calibrated around the CRX's incredibly light chassis and short wheelbase, the Spec-RS delivers immediate steering response, exceptional chassis control, and the consistency needed for autocross, canyon driving, and repeated track sessions.
Dežru Spec-RS Coilovers – 88-91 Honda CRX
The Dežru Spec-RS coilover system is engineered specifically for the 1988-1991 Honda CRX. Weighing hundreds of pounds less than most modern performance cars, the CRX remains one of the most responsive front-wheel-drive chassis ever built. Its lightweight construction, short wheelbase, and direct steering create an experience few vehicles can match.
The challenge with the CRX is that every suspension change is immediately noticeable. Excessive spring rates can make the chassis nervous, while insufficient support allows excessive roll and weight transfer. The Spec-RS was developed to strike the ideal balance between responsiveness, grip, and driver confidence.
Developed on a shaker rig for serious enthusiasts and weekend track drivers, the Spec-RS features digressive piston valving that delivers exceptional chassis support under load while maintaining compliance over uneven pavement. Combined with external rear reservoirs, this system provides improved thermal consistency and fade resistance during extended lapping, autocross competition, and aggressive canyon use.
With fixed-length damper bodies and a 30–45 mm adjustable lowered ride height, the Spec-RS maintains proper stroke, geometry, and bump travel, ensuring the CRX remains composed, predictable, and confidence-inspiring at every corner.
Key Features
- Digressive monotube dampers for superior control, consistent damping, and precise driver feedback tuned specifically for the EF CRX chassis.
- External rear reservoirs for improved heat dissipation and fade-resistant performance during continuous high-load use.
- Fixed-length damper bodies with 30–45 mm adjustable lowered ride height for optimal geometry and bump travel retention.
- Adjustable damping to fine-tune rebound for street, canyon, autocross, or track conditions.
- 400 lb/in front & 350 lb/in rear spring rates — optimized for lightweight chassis balance and maximum responsiveness.
- Linear HyperCoil springs ensure predictable response and smooth load transition through every phase of the corner.
- Pillowball front top mounts for sharper steering feedback and improved alignment consistency.
- Hand-built, dyno-matched pairs to ensure precise left-right damping uniformity.
Performance Character
The Spec-RS amplifies everything enthusiasts love about the CRX. Steering response becomes even more immediate, transitions become quicker, and body motions are better controlled without sacrificing the lively nature that makes the chassis so enjoyable.
The digressive valving curve provides firm low-speed damping for platform control, steering accuracy, and body motion management while maintaining enough compliance to keep the tires working effectively over real-world pavement. This allows the chassis to remain responsive without becoming nervous or unpredictable.
Under braking, the front end remains more composed. During turn-in, the chassis reacts immediately to driver input. Through mid-corner load, the vehicle feels planted and communicative. On corner exit, the suspension effectively manages weight transfer to maximize traction and maintain balance.
The result is a CRX that feels sharper, flatter, and more capable while retaining the playful character that made the chassis legendary.
Why We Recommend 400 lb/in Front & 350 lb/in Rear for the 1988-1991 Honda CRX
The EF CRX is one of the lightest performance platforms Honda ever produced. Because of its low curb weight and short wheelbase, spring selection becomes critically important. Rates that work well on heavier Civics and Integras can easily overpower the CRX chassis and reduce grip.
Our 400 / 350 spring rate setup was selected specifically for Spec-RS to maximize responsiveness and chassis control while preserving the vehicle's natural agility.
The 400 lb/in front spring provides the support necessary to reduce braking dive, improve steering precision, and maintain more consistent front tire loading during aggressive corner entry.
The 350 lb/in rear spring complements the front rate by promoting rotation while maintaining stability. This pairing allows the chassis to remain responsive and eager to change direction without becoming overly reactive during high-speed transitions.
The result is a setup that:
- Significantly reduces body roll and brake dive
- Improves steering precision and front-end response
- Maintains predictable chassis balance
- Enhances rotation without creating instability
- Increases confidence during aggressive driving
This pairing is designed to work with our Spec-RS valving, which provides strong low-speed damping for immediate chassis response and increased high-speed control for track conditions. Together, the spring and damper package delivers a highly connected and confidence-inspiring driving experience.
Compared to softer street-focused setups, this configuration prioritizes precision, feedback, and consistency while respecting the unique characteristics of the lightweight CRX chassis.
Overall, 400 front / 350 rear gives the CRX a sharper, more responsive, and more track-capable character while preserving the balance and agility that made the EF chassis an icon.
