Mazda RX-7 (FC3S) 1987-1992 - 520 Series Club Racer Coilovers



Fortune Auto engineers found a need in the market for a capable 2-Way adjustable, prosumer Motorsports coilover system. The result? The Generation 8 - 520 Series Club Racer.

The 520 Series double adjustable coilover is a remarkably sophisticated damper system. The compact system has a 2-Way adjustable canister that is tuned to the specific chassis. The canister is mounted directly to the shock to provide ease of installation and a more plug and play system. 

Utilizing the highly advanced, Concave Flow Digressive Piston to provide an incredibly dynamic adjustment range along with the ability to upgrade and rebuild; you‘ll never have to buy coilovers again.

      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.

      520 Series Coilovers are custom, hand-built to order. Most applications have a 4-7 week lead time. Lead times for certain applications and peak season orders may vary.
