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

The C5 and C6 Corvette have a chassis problem that gets louder the harder you push them: Magnetic Selective Ride Control was clever for a 2000s GT, but on a circuit it’s a closed loop you can’t tune around, and once a shock unit fails the replacement cost is brutal. The Circuit Master coilover for the Corvette C5/C6 is built around that exact reality – a full mechanical replacement with the electronic damping cancellation kit included, so the car runs on a damper platform you control with a spanner, not a reflashed ECU.

For sustained lap-time work in a transverse-leaf Corvette, this is the spec XYZ Racing built for Racing, Drift and Tarmac Rally use. It is not a fast-road compromise. It is the kit you fit when the car is going to spend weekends at Anglesey, Donington or Spa and you need consistent damper behaviour from session one to session six.

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

Replacing MagneRide with a 9720-way mechanical platform changes the car. Front-end response sharpens because the damper is no longer chasing an algorithm – you set compression and rebound, the car holds the setting, and the front tyre loads predictably under trail-braking into a long third-gear corner. The rear, traditionally where C5 and C6 owners report mid-corner squat under power, can be wound up to match the spring rate of your slick or semi-slick choice. Ride height comes down evenly without the geometry surprises that bolt-on lowering springs introduce. And critically, the electronic damping cancellation kit removes the dashboard warning loop, so the car drives without fault codes throwing it into a limp strategy mid-stint.

About the Circuit Master coilover

The Circuit Master sits at the top of XYZ Racing’s competition tier, alongside the Racing Spec, Drift Spec and Tarmac Rally builds. It is a three-way adjustable damper – three separate knobs covering the rebound and compression curves – giving 9720 distinct damper settings across the unit. The architecture has been tested by XYZ racing teams on international circuits, with the calibration window pushed toward track surfaces rather than potholed B-roads. The small-oil-hole design inside the three adjustment circuits is a deliberate trade-off: at race speeds across kerbs and circuit transitions it gives precise damper response, and on big road bumps that geometry can produce a faint audible passage of oil through the smaller orifices. That is not a fault. It is the cost of the resolution you get when you want to find a setting between two laps on a hot Friday and have it still be there on Sunday morning.

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

Chassis code CH08-C, covering Corvette C5 (1997-2004) and C6 (2005-2013) variants originally equipped with Magnetic Selective Ride Control. The kit ships with the cancellation harness needed to deactivate the factory electronic damping circuit on both generations. Confirm your VIN-build matches the MagneRide-equipped trim before ordering – non-MagneRide C5/C6 cars take a different XYZ Racing part number.
