Dežru Spec-RS • Track First Honda S2000 (AP1 / AP2)

Built for high-rev grip, response, and confidence at the limit.

Calibrated around the S2000’s high-rev character and quick steering, the Spec-RS delivers firm, communicative damping with the heat capacity and control needed for repeated track sessions and aggressive canyon runs.

Digressive pistons (track-focused) Heat-resistant valving Sharp turn-in & mid-corner support Tuned for AP1 / AP2 chassis dynamics

Dežru Spec-RS Coilovers – Honda S2000 (AP1 / AP2 2000–2009)

The Dežru Spec-RS coilover system is the pinnacle of precision for the Honda S2000 chassis — a platform renowned for its purity and razor-sharp handling. Designed around the S2000’s double-wishbone geometry, the Spec-RS brings uncompromising control and modern race-bred damping technology to an already exceptional sports car.

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 achieves superior thermal consistency and fade resistance during extended lapping or canyon sessions.

With fixed-length damper bodies and a 30–45 mm adjustable lowered ride height, the Spec-RS maintains proper stroke, geometry, and roll center correction — ensuring the S2000 feels composed and confidence-inspiring at every corner entry and exit.

Key Features

Digressive monotube dampers for superior control, consistent damping, and precise driver feedback tuned specifically for the S2000.
External rear reservoirs for improved heat dissipation and fade-free 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, or track conditions.
575 lb/in front & 450 lb/in rear spring rates — perfectly balanced for fast road + HPDE driving.
Linear HyperCoil springs ensure predictable response and smooth load transition through each phase of the corner.
Pillowball front top mounts for sharp steering feedback and alignment consistency.
Hand-built, dyno-matched pairs to ensure precise left-right damping uniformity.

Performance Character

The Spec-RS elevates the S2000’s natural balance and steering precision while offering vastly improved chassis composure under braking, transitions, and sustained cornering loads. The digressive valving curve provides firm, supportive damping on compression with a smooth, compliant rebound response — ideal for high-grip tires and spirited driving.

Expect a flat, confident, and responsive feel on turn-in, with the compliance and traction to put power down hard out of every corner — lap after lap.

Why We Recommend 575 lb/in Front & 450 lb/in Rear for the Honda S2000

The Honda S2000 is a lightweight, rear-wheel-drive platform with a near 50/50 weight distribution and extremely responsive chassis dynamics. From the factory, it is already a sharp car, but at higher limits it can feel nervous and sensitive to weight transfer, especially during rapid transitions or aggressive driving.

Our 575 / 450 spring rate setup is designed to stabilize the chassis and increase precision, making the car more predictable and confidence-inspiring at the limit.

By running a higher spring rate in the front, we increase front-end support during braking and corner entry. The 575 lb/in front spring reduces dive, sharpens steering response, and helps keep the front tires more consistently loaded under aggressive driving conditions.

In the rear, the 450 lb/in spring is carefully selected to maintain traction and control. Keeping the rear slightly softer relative to the front helps prevent snap oversteer and keeps the car progressive and manageable, while still providing enough support for high-speed cornering and transitions.

The result is a setup that:

Improves front-end precision and steering response
Reduces dive and excess chassis movement
Maintains rear traction and predictability
Increases confidence during aggressive driving

This pairing is designed to work with our more aggressive valving, delivering strong low-speed damping for immediate response and increased high-speed control for track environments. The combination of spring and damping provides a highly connected and predictable driving experience.

Compared to softer, street-focused setups, this configuration prioritizes stability, precision, and driver confidence, making it ideal for track use, autocross, and aggressive driving scenarios.

Overall, 575 front / 450 rear gives the S2000 a more planted, controlled, and confidence-inspiring character, allowing the driver to push harder with greater precision and consistency.
