Dežru Spec-A Coilovers – Subaru WRX (2015–2021)

The Dežru Spec-A is engineered specifically for the VA chassis WRX, focusing on delivering a more comfortable and composed daily driving experience.

Many aftermarket coilovers for the WRX prioritize stiffness over usability, resulting in a harsh, busy ride that quickly becomes tiring. The Spec-A avoids that by using balanced spring rates and properly matched damping to improve control without sacrificing comfort.

With a lowering range of 0.5" to 3" below OEM ride height, the Spec-A provides the stance most owners want while maintaining proper suspension geometry and usability.

Performance Character

The Spec-A transforms the WRX into a more refined and comfortable daily driver. It reduces harshness and impact stiffness while maintaining enough control to keep the car feeling planted and predictable.

The front spring rate maintains compliance over rough roads, while the slightly higher rear rate helps stabilize the chassis under acceleration and cornering. This creates a balanced feel that improves confidence without introducing stiffness.

Around town, the ride is smooth and forgiving. On the highway, the car feels stable and composed. When pushed on backroads, the suspension maintains control without becoming harsh or tiring.

While designed primarily for comfort, the Spec-A is still capable of spirited driving and occasional autocross, making it a versatile option for daily-driven WRXs.

Who This Is For

Drivers who want a comfortable, lowered daily driver
Those tired of harsh, overly stiff coilovers
Street-focused builds with occasional spirited use
Owners who value ride quality and composure

If your goal is a WRX that looks right, rides well, and feels composed in everyday driving, the Spec-A is built for exactly that.
