Description
Upgrade your Subaru WRX’s handling and chassis control with the Dežru Spec-S Coilover System, engineered for drivers who want sharper response, improved stability, and a more connected driving experience without giving up everyday usability.
Designed for the 2015–2021 Subaru WRX VA chassis, the Spec-S combines digressive inverted monotube dampers, adjustable damping, and matched 450 lb/in front and rear spring rates to deliver a performance-focused suspension setup for daily driving, spirited back-road runs, autocross, and occasional HPDE track events.
Rather than relying on excessive spring stiffness, the Spec-S uses carefully developed damper valving to help manage body movement during braking, cornering, and acceleration. Its digressive damping profile is designed to provide strong control during initial suspension movements while maintaining compliance over uneven pavement, helping the WRX feel more composed on the street and more predictable when driven enthusiastically.
The system targets a ride frequency of approximately 1.9–2.2 Hz, aiming for a balance between responsive handling and practical street comfort. Combined with linear HyperCoil springs and OEM-style upper mounts, the Spec-S offers a well-rounded upgrade for WRX owners seeking improved suspension performance without an unnecessarily harsh setup.
The fixed-length inverted damper bodies support an adjustable lowered ride height of approximately 25–50 mm, allowing you to tailor the vehicle’s stance while maintaining a suspension design focused on usable travel and consistent handling. Proper installation and alignment are recommended after adjusting ride height.

Performance Benefits
Improved Body Control
The Spec-S damping package is designed to help reduce excessive body movement during braking, cornering, and directional transitions. This can give the WRX a more controlled feel when entering corners, changing direction, or navigating winding roads.
Responsive Steering and Chassis Feedback
The combination of digressive damping and 450 lb/in front and rear springs is intended to deliver a more immediate, connected driving experience. Drivers can fine-tune damping to suit their preferences and driving conditions.
Balanced Street and Performance Use
With a target ride frequency of approximately 1.9–2.2 Hz, the Spec-S aims to combine performance-oriented control with practical road manners. Actual ride comfort will depend on road conditions, tire selection, alignment, vehicle configuration, and damper settings.
Adjustable Lowered Stance
The approximately 25–50 mm lowering range allows owners to adjust the WRX’s ride height to suit their preferred appearance and setup. A professional alignment is recommended after installation or ride-height changes.
Why Choose 450 lb/in Front and Rear Spring Rates?
The 2015–2021 Subaru WRX is designed to deliver everyday comfort alongside the traction and versatility of its all-wheel-drive platform. For drivers seeking a more performance-focused setup, the Dežru Spec-S pairs 450 lb/in front and 450 lb/in rear springs with purpose-developed digressive damping to provide a firmer foundation for controlling chassis movement.
The equal nominal spring rates create a straightforward starting point for suspension tuning. However, the vehicle’s overall handling balance also depends on suspension geometry, motion ratios, anti-roll bars, alignment, tires, and damper calibration. The matched rates should therefore be viewed as part of a complete suspension package rather than a guarantee of neutral handling in every condition.
At the front, the spring and damper combination is designed to provide support during braking and corner entry. At the rear, the matching nominal rate contributes to the overall chassis-control strategy as the vehicle accelerates and transitions through corners.
Combined with adjustable damping, this setup gives drivers the flexibility to refine suspension response for everyday commutes, spirited street driving, and occasional performance events.
The result: a more performance-oriented WRX suspension setup designed to improve body control and driver confidence while retaining the versatility expected of a daily-driven sports sedan.
Who Is the Dežru Spec-S For?
The Dežru Spec-S is a strong option for Subaru WRX owners who want to:
-
Improve suspension control during spirited driving.
-
Reduce excessive body movement through corners and transitions.
-
Lower the vehicle by approximately 25–50 mm.
-
Fine-tune damping for personal preferences and driving conditions.
-
Maintain a practical setup for everyday road use.
-
Enjoy occasional autocross or HPDE events without choosing an exclusively track-focused suspension.
