XYZ Racing Circuit Master Coilovers — Chevrolet CORVETTE C7 (Cancellation Kit for Electronic Damping) 2013-2019

The C7 Corvette’s Magnetic Ride Control was a clever bit of GM engineering, but it’s also the first thing serious track drivers want gone. MR shocks bleed performance once heat-soaked over consecutive sessions, and the closed ECU strategy fights any real attempt at corner-weight or rebound tuning. The Circuit Master coilover swaps that whole electronic compromise out and replaces it with a mechanical platform built for sustained circuit lap-time work – and the supplied cancellation kit means the dash stops nagging about it.

This is XYZ Racing’s most serious damper, the one used on their international Racing Spec, Drift Spec and Tarmac Rally programmes. For a 460-650bhp LT1 or LT4 C7 being driven hard at Donington, Cadwell or Spa, that pedigree is the point.

What this coilover does for your 2013-2019 Chevrolet Corvette C7

With Magnetic Ride deleted, the front-mid weight balance of the C7 finally has a damper that can be set to it rather than around it. The 9720 individual damping permutations mean you can run a stiffer high-speed compression curve for the long sweepers without making the kerbs over T8 unrideable on the low-speed side. Brake stability improves noticeably once front rebound is calmed down – the nose stops pitching into the carbon ceramics on the Z06/Z51 cars, and turn-in becomes a decision rather than a reaction. Rear traction off corner under full LT1 torque comes back too, because you’re now setting bump in a way the OE MR strategy never let you. The cancellation kit handles the CAN message side so there’s no fault codes, no limp mode, no MR warning light staring back at you on the in-lap.

About the Circuit Master coilover

The Circuit Master is the top of XYZ Racing’s competition range and shares its construction DNA with their Racing Spec, Drift Spec and Tarmac Rally dampers. Three separate adjustment knobs give independent control over compression and rebound across a 9720-way matrix – the kind of granularity that only matters when you’re chasing the last two tenths over a 20-lap stint. The dampers have been developed and validated by XYZ Racing teams competing on circuits worldwide, with the brief weighted firmly toward consistency under heat and repeat-lap abuse rather than road comfort. One trait worth knowing up front: the small oil-passage design that gives the Circuit Master its tight high-frequency control will produce a faint hydraulic note when hitting larger bumps. That is intentional and inherent to the valving – this damper is built for track surfaces, not broken B-roads.
