Balanced daily comfort with real back-road capability.
Designed to lower your car by approximately 25–30 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 – 2014–2024 Mini Cooper (F56 / F55 / F57)
The Dežru Spec-S coilover system is engineered specifically for the 2014–2024 Mini Cooper platform, a lightweight, short-wheelbase chassis that rewards precise damping and well-matched spring rates. Designed around the Mini’s low mass, high roll sensitivity, and playful handling characteristics, the Spec-S delivers sharper response, improved stability, and significantly better control without compromising daily drivability.
Developed for drivers who daily their Mini but still enjoy spirited street driving, canyon roads, autocross, and occasional HPDE track days, the Spec-S features digressive piston valving that provides strong low-speed chassis 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 ~2.1–2.4 Hz range, tightening the platform while preserving the Mini’s character and ride quality.
Fixed-length damper bodies paired with a 25–35 mm adjustable lowered ride height ensure proper suspension stroke and geometry are maintained. This preserves usable bump travel and predictable roll behavior, allowing the Mini to remain composed and confidence-inspiring during aggressive driving.
Key Features
-
Digressive monotube dampers for excellent body control, consistent damping performance, and precise driver feedback.
-
Fixed-length damper bodies with 25–35 mm adjustable lowered ride height to preserve suspension geometry and usable travel.
-
Adjustable damping to fine-tune rebound for daily driving, back roads, autocross, or HPDE track use.
-
550 lb/in front and 650 lb/in rear spring rates, selected to reduce body roll, sharpen turn-in, and maintain rear stability without 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 Mini Cooper by significantly reducing excess body motion and improving stability while retaining the car’s fun, agile nature. The digressive damping profile provides immediate 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 that feels sharper, more planted, and more confidence-inspiring, remaining comfortable for daily use while delivering the control and responsiveness needed for aggressive driving.
