XYZ Racing Circuit Master Coilovers — Chevrolet CORVETTE C5/C6 1997-2013

The C5 and C6 Corvette is a long, wide, transaxle-balanced GT with serious mechanical grip on tap – and a chassis that punishes anyone running road-biased damping when the lap timer comes out. Heat soak in the dampers, mid-corner float over kerbs, and that characteristic C5/C6 rear-end shimmy when you load the LS up on exit are all damping problems before they are anything else. The Circuit Master coilover is XYZ Racing’s answer for owners who actually use the circuit.

For sustained lap-time work in a C5 Z06 or C6 base/Z51, this is the spec to specify. It sits at the top of XYZ’s competitive ladder alongside the Drift and Tarmac Rally builds, and it is built to keep working when a softer fast-road kit would have given up three laps ago.

What this coilover does for your 1997-2013 Chevrolet Corvette C5/C6

The Circuit Master gives you three separate damping knobs – high-speed compression, low-speed compression, and rebound – which is exactly the level of control a transaxle Corvette wants for repeat-session circuit use. You can run a firmer high-speed setting to control the C6’s tendency to ride down on its bump-stops over kerbs, while keeping low-speed compliance manageable for the on-throttle weight transfer the LS sends rearward. The result is a Corvette that turns in flat, holds its line through long radius corners like Copse or Old Hall, and stops squirming on power exit. Spring preload and ride height are independently adjustable, so you can drop the nose to kill the C5/C6’s slight high-speed front lift without losing usable travel.

About the Circuit Master coilover

Circuit Master sits at the top of XYZ Racing’s competitive line, alongside the Drift Spec and Tarmac Rally builds, and it is the spec the brand puts forward for international circuit use. The damper has been developed and tested by XYZ race teams worldwide rather than tuned only on a dyno. The headline number is 9720 distinct damping combinations across the three adjustment knobs, which is the practical reason a single kit covers a winter Donington setup, a summer Spa setup, and a quick fast-road compromise without ever needing a re-valve. One thing to know up front: the small oil passages inside the three-knob valving can produce a faint metering noise over big road bumps. That is the trade for the circuit damping resolution and is normal behaviour – this kit is built for track surfaces, not B-road potholes.

Fitment for the Chevrolet CORVETTE C5/C6 (1997-2013)

Engineered specifically for the Chevrolet Corvette C5 and C6 chassis (XYZ chassis code CH08) covering the 1997 to 2013 model years. The kit replaces the factory monoleaf/coilover setup on all four corners. Confirm your year and trim against the listed range before ordering – the C5 and C6 share a fundamental chassis architecture which is why XYZ groups them on a single platform code.
