Fortune Auto engineers are consistently chasing improvement and the development of the Generation 8 – 510 series dampers is no exception. The 510 Series single adjustable coilover is a remarkably sophisticated damper system that utilizes the highly advanced, Concave Flow Digressive Piston to provide an incredibly dynamic adjustment range along with the ability to upgrade and rebuild. All systems are built completely in-house by Fortune Auto in Richmond, Virginia.

No Revalves Necessary

The ultra wide range of adjustment offered by the 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.

Jekyll and Hyde

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.
