Description
The Dežru Spec-A Coilover System for the 2015–2021 Subaru WRX STI is designed to improve ride comfort, suspension control, and everyday drivability while preserving the sharp handling character of the VA-chassis STI. Featuring comfort-focused monotube dampers, adjustable rebound damping, and balanced spring rates, the Spec-A offers a refined suspension upgrade for drivers who want better road manners without sacrificing chassis composure.
The Subaru WRX STI is engineered for performance, but aggressive aftermarket suspension setups can introduce excessive stiffness and harsh impacts on uneven roads. The Dežru Spec-A takes a more balanced approach, aiming to reduce unnecessary harshness and excessive body movement while maintaining predictable handling and support during spirited driving.
With an adjustable lowering range of approximately 0.5–3 inches below OEM ride height, the Spec-A allows owners to customize the STI's stance while tailoring the suspension to their driving preferences. The final ride height should account for suspension travel, tire clearance, alignment, and everyday road conditions.

Performance and Ride Characteristics
The Dežru Spec-A is designed to refine the STI's driving experience by improving suspension compliance and reducing unnecessary harshness while maintaining a controlled, performance-oriented feel. Its comfort-focused damping and balanced spring rates aim to help the vehicle feel more settled over uneven pavement without becoming excessively soft or disconnected.
The approximately 392 lb/in front spring rate is intended to provide front-end support during steering inputs and braking, while the approximately 448 lb/in rear spring rate offers additional rear spring support. Together, these rates are designed to promote predictable chassis behavior during cornering, acceleration, and directional changes.
For daily driving, the Spec-A aims to provide a more comfortable and less fatiguing ride. At highway speeds, it is designed to deliver a composed feel, while on winding roads it offers suspension control suited to spirited driving.
Although primarily intended for street use, the Spec-A may also suit occasional autocross, depending on the vehicle setup, alignment, tires, and driving conditions.
Adjustable Ride Height
The Spec-A offers an approximate lowering range of 0.5–3 inches below factory ride height, allowing owners to achieve anything from a modest drop to a more aggressive lowered stance.
Proper ride-height selection is important for maintaining suspension travel, tire clearance, and predictable handling. A professional wheel alignment is recommended after installation and ride-height adjustment.
