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

The 991 GT2 RS treats weight distribution as a design choice rather than a compromise. With the flat-six hung behind the rear axle and rear-wheel drive doing all the work, putting this car onto a gravel stage demands a suspension philosophy entirely different from circuit setup. The XYZ Racing Pro Rally coilover for the Porsche 991 GT2/RS addresses exactly that – replacing the PASM electronic damping via the supplied cancellation kit with direct-control competition hardware calibrated for loose-surface and winter rally use.

This is a build configuration for drivers already committed to competition. The absence of the hydraulic lift system on this fitment signals the intent: the car has shed one of its road-oriented features in favour of a cleaner competition package, and the suspension follows suit.

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

The GT2 RS’s rear weight bias – the structural signature of the 911 platform – becomes the central variable to manage when tarmac gives way to loose gravel or snow. The Pro Rally replaces PASM’s adaptive response with fixed, team-controlled damping, removing the unpredictability of an electronic system interpreting loose surfaces in real time. Ride height and spring rates become active setup decisions made in the paddock, not responses calculated by the car mid-stage. On gravel, that directness matters: the rear-engine pendulum effect arrives quickly, and the driver needs absolute confidence in what the suspension is doing beneath them.

About the Pro Rally coilover

Developed for rally competition on gravel and snow, the XYZ Racing Pro Rally is a professional-grade suspension system built for stage use. It comes in two distinct configurations: the amateur type installs directly onto the existing chassis without structural modification, serving competitors running club or national-level events at a standard preparation level. The professional type is fitted following bodywork modification, making it the right choice for teams running full preparation where the car body has been modified to accept competition-spec suspension geometry. Both configurations are built for the compliance, articulation, and predictable weight transfer that loose-surface rally driving demands – characteristics that differ fundamentally from the stiffness targets relevant to circuit suspension.

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

This kit is designed for the PO18-C chassis, covering the Porsche 991 GT2/RS from 2017 to 2026. The fitment is specific to cars without the hydraulic lift system and is supplied with a cancellation kit for the factory PASM electronic damping. Verify your car’s configuration against these parameters before ordering.
