XYZ Racing Gravel Rally Coilovers — Mazda RX7 FD3S 1991-2002

The FD3S RX-7 was built around a 13B-REW twin-turbo rotary and a chassis that rewards a driver willing to commit – but commit on a loose stage surface and the standard setup runs out of travel fast. The Gravel Rally coilover is the spec for owners who’ve stopped pretending the FD is a circuit-only car and want to use it on tarmac-and-gravel mixed events, fast forest tracks, and the kind of rough back-road work that pulverises a road-spec damper.

This is a long-travel, soft-but-controlled coilover tuned for grip on unsealed surfaces – the opposite philosophy to the Circuit Master most FD owners default to. It keeps the rotary’s weight settled over bumps, lets the front end load progressively into a turn, and stops the rear from skipping under power on broken surfaces.

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

Spring rates and damper valving on the Gravel Rally are pitched lower than the circuit kits, which lets the FD’s relatively light front-end work the tyre into a loose surface rather than skating across it. You feel that as front grip on turn-in over compressions where the standard car would push wide. Rebound damping is tuned to keep the rear axle planted between bumps, which on the FD3S matters because the chassis loves to over-rotate on lift-off – soft, controlled rebound damps that tendency without killing the rotation a rally driver actually wants. Ride height is raised to give realistic ground clearance for unsealed roads, and the wider damping adjustment band means you can soften it further for genuine gravel or firm it up for a wet rally tarmac stage without changing the kit.

About the Gravel Rally coilover

The Gravel Rally is the rally-spec series in the XYZ Racing range – a long-travel, height-raised coilover built for unsealed surfaces and broken roads where ground clearance and bump compliance matter more than peak grip on smooth tarmac. Construction is monotube with a large-bore piston and a high-flow valve stack, which lets the damper move oil quickly enough to soak up sharp inputs without packing down. Spring rates sit deliberately below the circuit and drag specs, paired with a softer rebound curve so the wheel can find the road on rebound rather than hopping. The kit ships with full damping adjustment so the driver can match the setup to surface and tyre choice. Pillowball top mounts are used where the FD’s strut geometry allows, and bushings are specified for repeat heat cycles and grit ingress rather than NVH refinement.

Fitment for the Mazda RX7 (1991-2002)

This kit is built specifically for the FD3S chassis across the full 1991-2002 production run, covering Series 6, 7 and 8 cars. It fits the standard front double-wishbone and rear multi-link layout without modification to the subframes. Confirm your car’s chassis code reads FD3S before ordering.
