Cusco Zero-3 Coilovers Subaru STI 2004

Designed for competition models, this coil-over suspension kit is designed for full ride height and full suspension stroke length, adjustable with light weight aluminum Mono-tube 24-step damping force damper for competition. Comes with camber adjustable plated, pillow-ball type upper mount and rubber upper seat.

Full-length / ride height adjustment system allow shock stroke length to adjust ride height and coilsprings preload to adjust initial spring rate separately. Ride height can be changed by twisting threaded shock absorber case while maintaining optimal suspension stroke.

These newly developed mono-tube shock absorbers offer 24-step damping force adjustments, giving you wide precise and detailed settings from street to professional competition use. Paired with CUSCO Pillow Ball Upper Mounts that replace the soft factory rubber upper strut mounts with solid high strength metal mounts and spherical (pillow ball) bushings, the system gives quick steering response and precise driving & braking control.

All Zero-3R components passed more than 500 hours of anti-rust salt spraying test, ensuring prevention of sticking brackets and cartridge together caused by rusting, keeping each coil-over kit clean and lasting longer.
