Balanced daily comfort with real back-road capability.
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 – 2008-2016 Mitsubishi Lancer Evo X
The Dežru Spec-S coilover system is engineered specifically for the 2008–2016 Mitsubishi Lancer Evolution X, a high-performance AWD platform that responds exceptionally well to properly matched spring rates and modern damper control. Designed around the Evo X’s weight distribution, MacPherson strut suspension geometry, and aggressive factory handling characteristics, the Spec-S delivers sharper turn-in, improved mid-corner stability, and significantly greater composure without sacrificing daily comfort.
Developed for drivers who daily their Evo X but still enjoy spirited street driving, back roads, autocross, and occasional HPDE track days, the Spec-S features digressive piston valving that provides strong low-speed support during braking, turn-in, and transitions, while remaining compliant over rough pavement and surface imperfections. Rather than relying on excessive stiffness, this setup targets a balanced ride frequency in the ~1.9–2.2 Hz range, improving body control while maintaining traction and predictability, which is critical for maximizing the AWD system’s effectiveness.
Fixed-length damper bodies paired with a 25–40 mm adjustable lowered ride height ensure proper suspension stroke and geometry are preserved. This maintains usable bump travel and consistent tire contact, preventing the harshness and instability often associated with over-lowered setups. The result is an Evo X that remains planted, responsive, and confidence-inspiring whether driven aggressively or used as a refined daily driver.
Key Features
-
Digressive monotube dampers for excellent body control, consistent damping performance, and clear driver feedback.
-
Fixed-length damper bodies with 25–50 mm adjustable lowered ride height to preserve suspension geometry and usable travel.
-
Adjustable damping to fine-tune rebound for daily driving, spirited back-road use, autocross, or HPDE track events.
-
450 lb/in front and 500 lb/in rear spring rates, selected to reduce body roll, sharpen turn-in, and maintain rear stability without introducing harshness.
-
Linear HyperCoil springs for predictable load transfer and smooth, consistent response throughout suspension travel.
-
OEM-style upper mounts to minimize 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 transforms the R56 Mini Cooper by significantly reducing excess body motion and improving stability while retaining the car’s lively, engaging feel. The digressive damping profile provides immediate chassis support during initial inputs and rapid transitions, paired with controlled compliance that keeps the tires planted as grip levels rise.
The result is a Mini Cooper that feels sharper, more planted, and more confidence-inspiring, remaining comfortable for daily driving while delivering the control and precision needed for aggressive use.
