XYZ Racing Circuit Master Coilovers — Porsche 991 GT2/ RS (without hydraulic lift system) 2017-2026

The 991 GT2/RS’s rear-engine layout concentrates the majority of its mass behind the rear axle – a weight distribution that, at the ride heights the car’s active aero package actually needs to function, makes damper consistency at the rear the controlling variable in circuit stability. Porsche’s PASM calibration is capable, but it was engineered to satisfy road-car legality alongside track performance. The Circuit Master coilover exists to resolve that tension in favour of the circuit.

Specifying this kit without the Hydraulic Lift System removes the last ambiguity about the car’s purpose. It will not be raised for car parks. It will run at circuit height – where the widebody’s aero geometry was designed to operate – and at that stance, the quality and adjustability of the suspension underneath is the difference.

What this coilover does for your 2017-2026 Porsche 991 GT2/ RS (without Hydraulic Lift System)

Running the 991 GT2/RS at circuit height without the factory HLS in play puts the full load management on the coilover setup. The Circuit Master’s three-knob architecture – fast compression, slow compression, and rebound – offers 9720 distinct adjustment positions, giving a setup engineer the resolution to match rear damping to the GT2 RS’s considerable rear-axle loading without sacrificing front-end compliance in the braking zone. Height adjustment at both ends allows the static stance to be matched to individual circuit demands. The small oil-passage construction within each knob maintains consistent damper response throughout a sustained session as thermal load builds.

About the Circuit Master coilover

Developed and validated through XYZ Racing’s own competition programme – tested on international circuits in Racing Spec, Drift Spec, and Tarmac Rally trim – the Circuit Master sits at the head of XYZ’s product range. Three independent knobs govern fast-compression, slow-compression, and rebound damping, combining for 9720 adjustment combinations: a figure that is only meaningful when the hardware is consistent enough to hold those positions under competition conditions. The small oil-hole design within each knob creates a precision flow restriction that gives each adjustment increment genuine on-circuit feel; over sharp road transitions it can produce a faint mechanical note, which is an expected characteristic of the construction and entirely absent on the smooth surfaces of a circuit track. The design is aimed at sustained competitive use – conditions where bump amplitude is predictable and session-length consistency is what separates good hardware from adequate hardware.

Fitment for the Porsche 991 GT2/ RS (without Hydraulic Lift System) (2017-2026)

Built to chassis reference PO18, this kit covers 991-generation GT2/RS variants without the factory Hydraulic Lift System across the 2017 to 2026 production run. The HLS-delete specification is a hard compatibility condition – cars that retain the factory front-axle lift mechanism use different mounting geometry and require a separate kit. Confirm your car’s build specification before ordering.
