Dežru Spec-S

Dežru Spec-S Coilover – Street & Sport Lowering Suspension with Digressive Valving

The Dežru Spec-S coilover is the perfect balance between daily comfort and sport handling. Built with inverted dampers and the renowned Bilstein COB digressive piston, the Spec-S controls body roll, dive, and squat while remaining smooth enough for city streets. Paired with HyperCoils springs optimized for length and rate, the Spec-S is ideal for the everyday driver who craves sharper steering response and weekend track confidence.

Key Features:

Inverted Damper Design
The Spec-S features inverted monotube dampers, a design that places the stronger shaft at the bottom and the body at the top. For the driver, this means:

Bilstein COB Digressive Piston Technology
At the heart of the Spec-S damper is a Bilstein COB digressive piston, tuned for both street comfort and track composure. Digressive valving allows the shock to respond softly over small bumps, keeping daily driving comfortable, but stiffens rapidly as piston speeds increase—controlling body roll, dive, and squat during aggressive cornering or hard braking. The result: compliant ride quality with race-inspired control when you need it.

HyperCoils Springs
Each kit is paired with HyperCoils springs, known worldwide for precision and consistency. Their linearity ensures predictable handling, while their high tensile strength and fatigue resistance guarantee long service life without sagging.

Optimized Lengths & Rates
Spring lengths and rates were carefully chosen to maximize performance without sacrificing comfort. The Spec-S strikes the elusive balance: supple enough for city streets, yet responsive and confidence-inspiring on a track day.

Built for the Dual Life
The Spec-S is designed for the everyday driver who craves more. Smooth and compliant during the weekday commute, yet sharp and poised when pushed hard on weekends. It’s suspension without compromise, made for enthusiasts who live between the street and the circuit.

Global Sourcing, U.S. Assembly

This global collaboration ensures the highest levels of performance and reliability, while U.S. assembly guarantees strict quality control and vehicle-specific precision.

FAQ: Spec-S Street Coilover

Q: What are digressive valving coilovers?
A: Digressive valving provides high low-speed damping for body control, then levels off at high shaft speeds for comfort. On the Spec-S, this means flat cornering and stable braking on track, but smooth absorption of potholes and bumps on the street.

Q: Are street coilovers comfortable for daily driving?
A: With Bilstein COB digressive pistons and HyperCoils springs, the Spec-S balances responsiveness and comfort. It’s sharp enough for spirited driving but compliant enough for daily use.

Q: Why are inverted dampers better for street performance?
A: Inverted dampers increase rigidity and reduce side-load deflection. For the driver, this translates into better steering precision and durability, especially during cornering and aggressive driving.
