ISR Performance PRO Coilovers - Mazda RX-7 86-91 FC3S

Our PRO Coilovers for the FC3S RX-7. The higher-end coilover line in our lineup, tuned for better damping control and overall performance than our Basic Coilovers, and set up for the kind of dual-purpose use that defines most FC builds: comfortable on the street, sharp on the track.

What It Does

Replaces the factory FC suspension with a fully adjustable coilover setup. 32-way damping adjustment gives you genuine tuning range across street commute, weekend canyon runs, and track days. The mono-tube design dissipates heat better than twin-tube alternatives, which matters once you start putting heat into the dampers on track. Front pillowball upper camber mounts let you dial in front alignment more aggressively than the factory rubber mounts allow.

Fitment

Fits the Mazda RX-7 FC3S, 1986 to 1991.
