XYZ Racing Gravel Rally Coilovers — Chevrolet CORVETTE C5/C6 (Cancellation Kit for Electronic Damping) 1997-2013

The Corvette C5 and C6 were never built with a loose surface in mind – LS-powered, transaxle-balanced, and tied to GM’s electronically controlled Magnetic Selective Ride dampers on the cars that carried it. Pull that system out for stage use and you need a damper that talks to gravel, not a magnetorheological fluid map written for Sebring tarmac. The XYZ Racing Gravel Rally coilover is that damper, and the kit ships with the electronics cancellation hardware so the car stops fighting the missing OE signal.

This is a purpose-shaped rally damper for a chassis that already has the engine, the rear weight bias and the LSD to be quick on a stage. The Gravel Rally spec lets the Corvette use that powertrain on the surfaces a road-spec C5 or C6 would simply skate across.

What this coilover does for your 1997-2013 Chevrolet Corvette C5/C6 (Cancellation Kit for Electronic Damping)

Long stroke is the headline. A gravel-spec C5 or C6 needs to swallow ruts, compressions and yumps without bottoming the chassis onto the bumpstop, and the long-travel, long-spring layout here is built around exactly that. The inverted-tube construction puts the bigger, stiffer body at the top of the strut where the bending loads are – the right way round for cars that pound through compressions all day.

Spring rates are set softer and longer than any tarmac coilover XYZ make, so the C5/C6’s relatively light front end can keep the tyre loaded over broken surfaces instead of skipping. The cancellation kit removes the OE damper signal cleanly, so there is no dashboard fault flag and no ride-control module fighting a damper it cannot see. The result on stage is a Corvette that uses its torque instead of wasting it spinning a wheel that has just left the ground.

About the Gravel Rally coilover

XYZ Racing developed this damper specifically for rally and rallycross, where the surface is the most aggressive a damper will ever see. The inverted-tube architecture is the structural answer to that brief – it gives the strut the strength to take sandstone, snow and silt hits without flexing the shaft.

Stroke and spring length are both longer than a circuit damper, which is what lets the chassis absorb high-speed bouncy sections and carry G-force through fast turns without running out of travel. All spring rates in this specification have been tested by rally teams running the platform in competition, so the baseline you receive is a working stage setup rather than a catalogue default. The cancellation kit included in this part number disables the Corvette’s electronic damping control so the car can run a fully mechanical, driver-tuneable damper.

Fitment for the Chevrolet CORVETTE C5/C6 (Cancellation Kit for Electronic Damping) (1997-2013)

This kit covers Corvette C5 and C6 chassis (XYZ chassis code CH08-C) across model years 1997 to 2013. The "Cancellation Kit for Electronic Damping" designation means this part number is for cars originally fitted with GM’s electronic damper control – the kit removes that system and replaces it with a fully manual coilover. Confirm your car’s OE damper system before ordering.
