Everyday comfort with improved stability and control.
Designed to lower your car by approximately 25–50 mm while maintaining composure over real-world roads, the Spec-S sharpens turn-in and body control without beating you up on the commute.
Dežru Spec-S Coilovers – Subaru Forester (2014–2018)
The Dežru Spec-S coilover system is engineered specifically for the Subaru Forester, a versatile AWD platform designed for daily driving, light adventure use, and all-weather capability. From the factory, the Forester is tuned for comfort, often resulting in excessive body roll, noticeable pitch under braking, and a less controlled feel during transitions.
The Spec-S is designed to refine the Forester’s driving dynamics without compromising its everyday usability. Built for drivers who want better stability, improved control, and increased confidence on the road, this system delivers a more composed and predictable driving experience while maintaining ride comfort.
Utilizing digressive piston valving, the Spec-S provides strong low-speed damping to control body motion during braking, acceleration, and cornering, while remaining compliant over rough pavement and uneven road surfaces. Rather than relying on excessive spring stiffness, this setup targets a balanced ride frequency in the ~1.6–1.9 Hz range, ideal for a compact SUV platform.
Fixed-length damper bodies are designed to preserve suspension travel and maintain proper geometry, ensuring the Forester remains stable, predictable, and comfortable in a wide range of driving conditions.
Key Features
-
Digressive monotube dampers for improved body control, consistent performance, and confident handling.
-
Fixed-length damper design to preserve suspension travel and maintain proper geometry.
-
Adjustable damping to fine-tune ride quality for daily driving or more controlled, responsive behavior.
-
400 lb/in front and 450 lb/in rear spring rates, selected to reduce body roll while maintaining comfort and improving rear load support.
-
Linear HyperCoil springs for predictable load transfer and consistent ride characteristics.
-
OEM-style upper mounts to minimize noise, vibration, and harshness.
-
Hand-built, dyno-matched pairs for consistent damping performance left to right.
Performance Character
The Spec-S transforms the Subaru Forester by significantly reducing excess body motion and improving overall chassis composure. The vehicle feels more planted in corners, more controlled during braking, and more stable during lane changes and highway driving.
The slightly higher rear spring rate improves support under load, helping reduce squat and rear-end movement when carrying passengers or cargo. The front rate maintains compliance for comfort while improving steering response and front-end control.
Combined with digressive damping, this results in a smooth, controlled ride that adapts well to real-world driving conditions. The Forester retains its comfort and versatility while gaining a more confident and connected driving feel.
Why We Recommend 400 lb/in Front & 450 lb/in Rear
The Forester’s factory suspension is tuned for comfort, which can lead to excessive body roll and a soft, less controlled feel—especially when loaded with passengers or cargo.
Our 400 / 450 spring rate setup is designed to correct that while maintaining the ride quality expected from a daily-driven SUV. The 450 lb/in rear spring provides additional support where it’s needed most, improving stability under load and reducing squat during acceleration.
Up front, the 400 lb/in spring adds control under braking and turn-in without making the ride harsh, allowing the suspension to remain compliant over rough roads.
The result is a setup that:
- Reduces body roll and overall chassis movement
- Improves stability during braking and transitions
- Adds rear support for passengers and cargo
- Maintains a comfortable, daily-driver-friendly ride
Overall, this pairing gives the Forester a more stable, planted, and confidence-inspiring feel while preserving the comfort and versatility that define the platform.
