XYZ Racing Super Sport Coilovers — Porsche 991 GT2/ RS (without hydraulic lift system) (Cancellation Kit for Electronic Damping) 2017-2026

The 991 GT2 RS sits at the extreme end of what Porsche builds for the road. Its rear-engined, rear-wheel-drive layout amplifies every suspension input – get the damper setup wrong and the car’s 700bhp becomes a liability; get it right and it is one of the most exploitable track tools ever bolted to number plates. The XYZ Racing Super Sport coilover kit for the 991 GT2 RS (2017-2026) replaces the factory PASM electronic damping architecture with a mechanically adjustable system, giving the driver full authority over exactly how the chassis behaves.

Factory PASM calibrates across a range of scenarios simultaneously, and its automatic interventions on damping rate are not always what a track-day or spirited fast-road driver wants. This kit cancels that electronic layer. You set the damping where you want it and it stays there.

What this coilover does for your 2017-2026 Porsche 991 GT2/ RS

Ride height adjustment lets you lower the GT2 RS to a stance that tightens the aero relationship between the car and the road – relevant given the 991.2’s large fixed rear wing and front splitter generate meaningful downforce even at road speeds. The 36-way damping range means you can run a compliant setting for the journey to the circuit, then firm up at the gate without tools beyond the supplied adjuster. On a chassis where the engine sits behind the rear axle, damper stiffness at the rear directly influences how progressively the car loads up under throttle – a too-stiff setup makes traction management abrupt where a well-chosen setting makes it exploitable. The Super Sport’s adjustment range covers both extremes.

About the Super Sport coilover

The Super Sport sits in XYZ Racing’s fast-road and weekend circuit bracket – enough adjustment depth to serve both environments without being a dedicated competition part. A 36-way adjustable damper forms the centrepiece: at its most compliant, it absorbs the kind of broken surfaces and expansion joints that make other stiffly-sprung cars exhausting on a long run; at its firmest, it suppresses the body movement that the GT2 RS’s power and aero loads would otherwise work against. Ride height adjustment runs through both axles, giving owners meaningful latitude over stance relative to factory geometry. Developed to neutralise rough-road harshness while retaining the adjustment depth that performance driving demands, the Super Sport is well-matched to how GT2 RS owners actually use these cars – fast roads on weekdays, circuits at weekends. The cancellation kit element removes the factory electronic damping logic, putting the 36-way mechanical adjuster in sole charge of damper behaviour.

Fitment for the Porsche 991 GT2/ RS (2017-2026)

Built for chassis code PO18-C, this kit covers the Porsche 991 GT2 RS across the full 2017-2026 model span. The specification is for cars not fitted with the hydraulic front axle lift system, and the cancellation kit is designed to replace the factory electronic damping – verify both against your build sheet before ordering. If your 991 carries either of those factory options, this kit is not the correct fitment.
