Sharper control for the 996 Turbo without turning it into a track car.
Designed specifically around the additional weight, power, and all-wheel-drive layout of the 996 Turbo, the Spec-S improves turn-in, body control, and high-speed stability while retaining the compliance needed for real-world street driving.
Dežru Spec-S Coilovers – Porsche 996 Turbo
The Dežru Spec-S coilover system is engineered specifically for the Porsche 996 Turbo, taking into account the additional weight, all-wheel-drive hardware, rear weight bias, and substantially higher performance capability of the Turbo platform.
Designed for drivers who use their 996 Turbo on the street but still enjoy spirited driving, mountain roads, and occasional HPDE track days, the Spec-S delivers improved stability, sharper response, and greater chassis control without sacrificing everyday usability.
The Spec-S uses digressive piston valving to provide strong low-speed chassis support during braking, turn-in, acceleration, and transitions while remaining compliant over rough pavement and surface imperfections. Rather than relying on excessive spring stiffness, the suspension combines properly selected Turbo-specific spring rates with matched damping to keep the car composed and predictable.
Fixed-length damper bodies paired with a 25–30 mm adjustable lowered ride height help maintain proper suspension stroke and geometry. This preserves usable bump travel and predictable suspension behavior while giving the 996 Turbo a lower, more purposeful stance.
Key Features
-
Digressive monotube dampers for controlled body motion, consistent damping performance, and clear steering feedback.
-
Fixed-length damper bodies with 25–30 mm adjustable lowered ride height to preserve suspension geometry and usable travel.
-
Adjustable damping to fine-tune rebound for daily driving, back-road use, or HPDE track events.
-
350 lb/in front and 600 lb/in rear spring rates, selected specifically for the additional weight, AWD hardware, rear weight bias, and performance capability of the 996 Turbo.
-
Linear HyperCoil springs for predictable load transfer and smooth, consistent response throughout suspension travel.
-
OEM-style upper mounts to reduce NVH while maintaining proper fitment and alignment consistency.
-
Hand-built, dyno-matched pairs to ensure precise left-to-right damping consistency.
Performance Character
The Spec-S gives the 996 Turbo greater chassis control without stripping away the compliance that makes the car enjoyable on real roads. Digressive damping provides immediate support during steering, braking, and throttle inputs while allowing the suspension to remain compliant over broken pavement and surface imperfections.
The result is a 996 Turbo that feels more planted, responsive, and predictable during aggressive driving while remaining comfortable enough for regular street use and longer drives.
For the 996 Turbo, the 350 lb/in front and 600 lb/in rear spring combination is selected around the Turbo's greater overall mass, all-wheel-drive system, rear-engine weight distribution, and substantially higher acceleration capability.
The 600 lb/in rear spring rate provides the support needed to control the considerable rear mass of the Turbo while resisting excessive squat under acceleration and maintaining suspension geometry as the rear tires are loaded. The additional rear rate improves stability and keeps the chassis composed during high-speed transitions without relying on excessive damping force to control the car.
Up front, the 350 lb/in spring rate accounts for the additional load introduced by the Turbo's all-wheel-drive system and associated front driveline hardware. Compared with the naturally aspirated Carrera, the Turbo requires additional front spring support under braking and cornering while still maintaining sufficient compliance and mechanical grip over imperfect surfaces.
The 350/600 combination maintains the intentionally rear-biased spring-rate relationship appropriate for a rear-engine 911 while increasing overall chassis support to match the Turbo's additional mass and performance capability.
Just as importantly, the dampers are specifically valved around these spring rates. Spring rate and damping work together as a system, allowing the Spec-S to provide stronger body control without simply making the suspension unnecessarily stiff.
On the street, the car remains compliant and usable. During spirited driving, the additional support becomes much more apparent, with reduced pitch and roll, more immediate response, and greater stability when accelerating out of corners. For occasional HPDE use, the combination provides the chassis control necessary to take advantage of the Turbo's performance without turning the car into a dedicated track setup.
Who This Is For
- 996 Turbo owners who want sharper handling without sacrificing street usability
- Drivers who regularly enjoy spirited street and back-road driving
- Owners looking for better body control and high-speed stability
- Street-focused cars that occasionally see autocross or HPDE use
- Drivers who want a meaningful performance upgrade without the harshness of a track-focused suspension
- Enthusiasts who want suspension tuning appropriate for the Turbo's additional weight, AWD system, and performance capability
If your goal is a 996 Turbo that feels more precise, controlled, and confidence-inspiring while remaining genuinely enjoyable on the street, the Spec-S provides the balance.
