Assembly, Regressive Valve

The age old racing damper setup dilemma has always been the compromise between low speed compression damping support which inspires driver confidence, and high speed compression damping for chassis control over bumps. Digressive style pistons allow increased low speed support only to the point where the resulting high speed damping levels begin to erode performance and tire wear. The regressive valve is the next logical step in eliminating this performance compromise.

Depending on track layout and vehicle set-up, it is recommended that regressive damping be tried on either compression or rebound. Typically we find compression regressive curves are most beneficial when curbing or large bump spikes are upsetting the car. Rebound regressive damping has shown advantages in help the vehicle recover quicker over bumps which allow the driver to return the throttle quicker.

This technology was born and developed in F1. Pioneering this patented technology, now all customers can benefit from this one of a kind technology.
