Dežru Spec-S Coilovers – Subaru WRX & STI (VA Chassis, 2015–2021)

The Dežru Spec-S coilover system is engineered specifically for the Subaru WRX and STI VA chassis, a capable AWD platform that benefits greatly from balanced spring rates and modern damper tuning. Designed around the VA’s suspension geometry, curb weight, and all-wheel-drive traction, the Spec-S delivers improved stability, sharper response, and greater confidence without sacrificing daily drivability.

Developed for drivers who daily their WRX or STI but still enjoy spirited street driving, back 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, expansion joints, and uneven surfaces. Rather than relying on excessive stiffness, this setup targets a balanced ride frequency in the ~1.9–2.2 Hz range, improving control and feedback while keeping the car comfortable on real roads.

Fixed-length inverted damper bodies paired with a 25–35 mm adjustable lowered ride height preserve proper suspension stroke and geometry. This maintains usable bump travel and predictable roll behavior, allowing the VA chassis to remain composed, stable, and confidence-inspiring during both daily driving and aggressive use.

Key Features

Digressive inverted monotube dampers for controlled body motion, consistent damping performance, and clear 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, spirited street use, autocross, or HPDE track events.
450 lb/in front and 450 lb/in rear spring rates, selected to deliver a neutral, predictable balance that enhances body control without making the car harsh or nervous.
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 VA WRX and STI by reducing excess body motion and improving overall chassis composure while retaining the AWD confidence and everyday comfort the platform is known for. The digressive damping profile provides immediate support during initial inputs, paired with controlled compliance that keeps all four tires planted as grip levels rise.

The result is a WRX or STI that feels balanced, predictable, and confidence-inspiring, remaining comfortable for daily driving while delivering the control and stability needed for aggressive street and track use.
