Built for precision, consistency, and confidence at the limit.
Engineered around the weight, power, all-wheel-drive system, and aggressive track demands of the 996 Turbo, the Spec-RS delivers elevated damping authority, sharper response, and heat-resistant performance to keep the chassis composed through long sessions and repeat hot laps.
Dežru Spec-RS Coilovers – Porsche 996 Turbo
The Dežru Spec-RS coilover system is engineered specifically for the Porsche 996 Turbo, a rear-engine, all-wheel-drive performance platform that demands precise damping control, substantial chassis support, and stability under heavy braking, high lateral loads, and aggressive throttle application.
Designed around the Turbo's additional mass, rear weight bias, AWD hardware, and significantly greater performance capability, the Spec-RS delivers a substantial increase in response, stability, and consistency when the car is driven aggressively.
Built for drivers who push their 996 Turbo hard on spirited roads, time attack, and HPDE track events, the Spec-RS features aggressive digressive piston valving with elevated rebound authority and firmer compression control compared with Spec-S. This allows the chassis to remain composed during rapid transitions, heavy braking, sustained lateral loading, and high-speed cornering while maintaining the compliance necessary to keep the tires working over curbing and surface imperfections.
Fixed-length damper bodies paired with a track-oriented adjustable lowered ride height preserve usable suspension stroke while maintaining proper suspension geometry. This approach keeps the Turbo predictable at the limit and stable during trail braking, power application, and corner exit, even when running high-grip tires.

Performance Character
The Spec-RS transforms the 996 Turbo into a sharper, more planted, and more predictable performance car at speed. Increased damping authority keeps the chassis settled during braking, turn-in, rapid transitions, and power application, while controlled high-speed compliance allows the tires to maintain contact over curbing and surface imperfections.
The 450 lb/in front spring rate provides the additional support required by the Turbo's all-wheel-drive front-end hardware while reducing pitch under heavy braking and improving response during rapid direction changes. Compared with the Spec-S, the increased front rate provides the platform control expected from a track-focused setup without abandoning mechanical grip.
At the rear, the 750 lb/in spring rate provides substantially greater support for the rear-mounted engine and the high longitudinal loads generated by the Turbo. The additional rate helps control squat under power, maintains suspension geometry during corner exit, and gives the rear axle the support required during sustained high-speed and high-grip use.
The 450/750 combination retains the intentionally rear-biased spring-rate relationship appropriate for the 911 platform while increasing overall chassis support to match the Turbo's weight and performance capability.
Spring rate is only part of the equation. The Spec-RS dampers are specifically valved to control these higher rates, with greater rebound authority and compression support than Spec-S. This allows the suspension to control platform movement without relying on spring stiffness alone.
The result is a 996 Turbo that responds immediately to driver inputs, remains stable as grip and speed increase, and maintains predictable balance through repeated high-load corners and braking zones.
While the Spec-RS can still be driven on the street, its priorities are deliberately shifted toward performance, precision, and track consistency. Drivers primarily concerned with comfort and daily use should consider Spec-A or Spec-S, while Spec-RS is intended for owners willing to trade some ride compliance for substantially greater control at the limit.
Who This Is For
- 996 Turbo owners who regularly participate in HPDE, time attack, or track events
- Drivers using high-performance or high-grip tires who need greater chassis support
- Enthusiasts looking for sharper transient response and improved stability under heavy braking
- Owners who prioritize precision and consistency over maximum street comfort
- Aggressive street and track builds that require more damping authority than Spec-S
- Drivers who want a track-focused suspension without moving to a more complex multi-way damper system
If your goal is to extract substantially more performance from the 996 Turbo while retaining the simplicity of a single-adjustable damper, the Spec-RS provides the additional spring rate, damping authority, and chassis control required for serious use.
