Cusco Sport ZERO-3 Competition coilovers are built for serious use. 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's solid high strength metal and spherical bushing pillow ball mounts, the system gives quick steering response and precise driving & braking control. The coilovers are double adjustable to allow for ride height setting done separate from spring preload to allow for maximum performance. All Zero-3 components pass a salt spraying test, preventing in sticking components caused by rusting, keeping each coil-over kit clean and lasting longer.
