XYZ Racing Circuit Master Coilovers — Porsche CAYMAN 718 (982) GT4 RS 2022-2026

The 982-generation Cayman GT4 RS already arrives as the most circuit-focused car in the Cayman line, with a naturally aspirated 4.0-litre flat six spinning to 9,000rpm and a mid-engine layout that rewards precise balance far more than raw grip. XYZ Racing’s Circuit Master coilover is built for Porsche owners pushing that platform further, into sustained circuit lap-time work where ride height, corner weight and damping all need to move together as track surface and tyre choice change.

Where the factory PASM setup is tuned to cover road driving as well as track days, the Circuit Master gives you the range to set the GT4 RS up for one job only: repeated laps at a chosen circuit, with the front splitter and rear diffuser sitting at the ride height you pick rather than the compromise Porsche built in.

What this coilover does for your 2022-2026 Porsche Cayman 718 GT4 RS

On a mid-engine chassis like the 982, small shifts in corner weight matter more than they would on a front-engined car, and full ride height adjustment lets you get the GT4 RS sitting level once you’ve added track tyres, a cage, or a different fuel load. The damping range lets you run stiff enough to control body movement through the fast, high-load corners this car is built for, without the front axle skipping over kerbs where the RS’s aero package is most sensitive to ride height changes. Because adjustment is external, you can retune the setup between sessions as track temperature or tyre compound changes rather than running one setting all day. On the 4.0-litre GT4 RS specifically, that keeps the flat six’s high-rev balance intact through direction changes, with less pitch and dive under trail braking into fast corners.

About the Circuit Master coilover

Circuit Master is XYZ Racing’s dedicated circuit-day design, built for cars that live on track rather than splitting time with road use. The damper offers 9720 combinations of compression and rebound adjustment across 3 external knobs, enough range to set a car up for a specific circuit and tyre rather than settling for one generic fast-road compromise. XYZ’s racing teams have run the design at circuits internationally during development, feeding lap-time data back into the valving rather than relying on bench figures alone. The knob assemblies use a small-bore oil path by design, so on rough sections of track you may hear a faint noise as oil moves through that passage; this is a normal characteristic of the damper, not a fault. The whole unit is built around circuit loading specifically, so kerb strikes and sustained high-speed cornering sit inside its design brief rather than being an edge case it merely tolerates.

Fitment for the Porsche Cayman 718 (982) GT4 RS (2022-2026)

This kit is built to the 982-chassis Cayman GT4 RS, covering the 2022 to 2026 model years. Confirm your car is the GT4 RS variant specifically, since its aero package and PASM-equipped suspension pickups differ from the standard Cayman and Cayman GT4 within this generation.
