Our revolutionary Concave Flow Digressive Piston Technology allows for a zero compromise track-oriented damper that has been developed for the track but still great for the street. The ultra-wide range of adjustment offered by our CFD Piston™ allows for the convenience of tuning your suspension without having to revalve your dampers. A conventional shock absorber can withstand a 2kg spring rate difference before requiring a revalve, whereas the Concave Flow Digressive Technology has a broad range of 8kg spring rates. This is invaluable for tuning your suspension quickly at the track on race day.

The Concave Flow Digressive Piston™ allows for a Jekyll and Hyde personality. Lower spring rates can be stiffened up by using the wide damping range as an artificial spring rate, while higher spring rates feel much smoother. The large adjustment range contributes to a comfortable ride on the street and unyielding performance on the track, all with the twist of a single adjustment knob. We utilize the CFD Piston™  in our 510 Series, Dreadnought Pro 2 Way, and 3 Way Coilover systems.
