XYZ Racing Super Sport Coilovers — Mazda RX7 FD3S 1991-2002

The FD3S RX-7 is one of the most balanced rear-drive chassis Mazda ever shipped, and it punishes poor damping more obviously than almost anything else from the era. Tired OEM struts on a 13B-REW car blur the steering, soften the mid-corner set, and make the rear feel nervous on throttle exactly where the twin-turbo rotary wants to commit. The XYZ Racing Super Sport coilover rebuilds that front-to-rear honesty, giving the FD back the pointy turn-in and tied-down rear it had in 1992.

This is the fast-road and trackday-focused kit in the XYZ range for the FD3S – stiffer and more deliberate than the Circuit Master, more liveable than the Drag or Tarmac Rally specs. It suits owners running a stock-twin or single-turbo 13B-REW who want sharper response without giving up the ability to drive the car home from a Cadwell evening session.

What this coilover does for your 1991-2002 Mazda RX7 FD3S

The Super Sport tightens the FD3S where it counts: front-end response under trail-braking and rear stability when the rotary’s mid-range torque arrives all at once. Pillowball top mounts replace the compliant OEM rubber, which is the single change that does most to sharpen the FD’s vague on-centre feel. Ride-height adjustment lets you reset corner weights after years of sagging OEM springs and reclaim factory geometry – or drop the car to dial out the slightly nose-up rake most FDs carry by now. Damping adjustment gives you a softer setting for B-roads and a firmer one for trackdays without swapping anything under the arches. The result is a car that finally rotates on the throttle the way the chassis engineers intended.

About the Super Sport coilover

The Super Sport is XYZ Racing’s circuit-capable street coilover – a 32-way damping-adjustable monotube built on the same hardware DNA as their full race kits, but valved for cars that still see daily or weekend road use. The damper bodies are CNC-machined, hard-anodised aluminium with EN24 chrome-plated piston rods running in a single high-pressure gas chamber, which keeps damping consistent through repeat heat cycles. Spring rates are matched to the FD3S chassis weight and intended use rather than a generic platform default, and the kit ships with pillowball upper mounts front and rear for direct, deflection-free load paths into the chassis. Ride-height adjustment is via the lower bracket rather than spring preload, so you can drop the car without losing usable stroke. Rebuildable and revalvable in service – this is a kit XYZ expects you to keep, not replace.
