Built for balance, precision, and confidence at the limit.
Engineered around the 944’s front-engine, rear-transaxle layout, the Spec-RS delivers sharper response, stronger platform control, and consistent damping performance for aggressive street driving and track use.
Dežru Spec-RS Coilovers – Porsche 944
The Dežru Spec-RS coilover system is engineered to complement the unique balance of the Porsche 944 chassis. With its front-engine layout, rear transaxle, and near-neutral weight distribution, the 944 rewards suspension tuning that improves response without disturbing the car’s naturally composed character.
Developed for serious street drivers, autocross use, canyon roads, and track-focused enthusiasts, the Spec-RS utilizes digressive piston valving to provide strong low-speed chassis support during braking, turn-in, and transitions, while maintaining controlled compliance over imperfect surfaces.
Fixed-length damper bodies paired with a 30–45 mm adjustable lowered ride height help maintain proper suspension stroke and geometry. This preserves usable bump travel and predictable roll behavior, allowing the 944 to remain stable, communicative, and confidence-inspiring during aggressive driving.
Key Features
-
Digressive monotube dampers for precise control, consistent damping behavior, and clear driver feedback.
-
Fixed-length damper bodies with 30–45 mm adjustable lowered ride height to maintain proper suspension geometry and usable stroke.
-
Adjustable damping to fine-tune rebound for street driving, canyon roads, autocross, or dedicated track use.
-
400 lb/in front and 550 lb/in rear spring rates, selected to support the 944’s transaxle layout while maintaining sharp front-end response, rear stability, and balanced rotation.
-
Linear HyperCoil springs for predictable load transfer and smooth response throughout the suspension travel.
-
Pillowball front top mounts for improved steering precision, alignment accuracy, and consistent feedback.
-
Hand-built, dyno-matched pairs to ensure precise left-to-right damping consistency.
Performance Character
The Spec-RS enhances the Porsche 944’s natural balance while adding a higher level of chassis control under braking, mid-corner loading, and corner exit. The digressive damping profile delivers firm, supportive control during initial inputs, paired with enough compliance to keep the tires loaded and predictable as grip levels rise.
The result is a flatter, sharper, and more communicative 944 that feels stable at speed, responsive on turn-in, and composed through quick transitions.
Why We Recommend 400 lb/in Front & 550 lb/in Rear for the Porsche 944
For the Porsche 944, a 400 lb/in front and 550 lb/in rear spring rate is a strong track-focused setup that respects the car’s transaxle balance and rear suspension geometry.
The 400 lb/in front spring gives the car the braking support and turn-in response needed for aggressive driving without making the front end overly stiff or vague over imperfect pavement.
The 550 lb/in rear spring provides the additional support needed at the rear, especially because the rear suspension motion ratio requires more spring rate at the coilover to achieve the correct wheel rate at the tire. This helps control squat, improves rear stability, and keeps the car from feeling lazy during transitions.
This pairing is designed around balance rather than brute stiffness. The 944 already has excellent natural weight distribution, so the goal is to sharpen the platform, reduce excess body motion, and keep the car predictable as speeds increase.
The result is a setup that:
- Improves front-end response and braking stability
- Reduces excess body roll and delay
- Adds rear support without making the car nervous
- Maintains the 944’s natural balance
- Works with the digressive valving instead of relying on excessive spring stiffness
Overall, the 400/550 combination gives the Porsche 944 a serious, controlled, track-capable feel while keeping the chassis communicative and predictable.
