XYZ Racing Pro Rally Coilovers — Porsche 991 GT3 (without hydraulic lift system) (Cancellation Kit for Electronic Damping) 2013-2019

The 991 GT3’s rear-biased weight distribution – a consequence of six decades of rear-engined Porsche architecture – shifts from a circuit-tuning variable into a legitimate competitive advantage on gravel or snow, where mass over the driven axle delivers exit traction that mid-engined rivals simply can’t match. Unlocking that potential requires suspension hardware built to a completely different brief than Porsche’s own PASM-managed road and track calibration.

This XYZ Racing Pro Rally coilover kit is developed for Porsche 991 GT3 owners competing in loose-surface disciplines – gravel stages, snow, and mixed-surface events where damping requirements shift every hundred metres. It addresses the factory electronic suspension directly: the kit is supplied with a cancellation module that allows the PASM system to be bypassed cleanly, removing ECU fault codes when the OEM dampers come out.

What this coilover does for your 2013-2019 Porsche 991 GT3

Rally surfaces impose loading patterns that a track coilover fights against – sharp compression crests, lateral ruts, and surface-to-surface transitions that demand travel and articulation well beyond what a circuit setup allows. The Pro Rally kit is calibrated for that environment, not for the sustained lateral g and smooth kerb inputs of a circuit application. Removing the factory PASM dampers also eliminates the electronically-managed compliance that works against committed stage driving; the cancellation kit handles the OEM control systems, leaving the coilovers to deliver repeatable, adjustable response without interference from adaptive modes. For a car as tightly engineered from the factory as the GT3, the option to install directly onto the unmodified body means the 991 can be returned to road or track use between events.

About the Pro Rally coilover

The XYZ Racing Pro Rally range is engineered for gravel and snow rally competition at two distinct levels of build commitment. The first configuration bolts directly to the existing GT3 chassis structure without requiring any bodywork modification – suited to owners running the 991 in hillclimbs, amateur stage events, or road-to-rally conversions where reversibility matters. The second is a full competition variant, intended for installation into a car that has had its body modified to accept the suspension geometry a serious stage programme demands. Both configurations are built around the specific load requirements of loose-surface competition: higher spring travel, damping tuned for unpredictable surface inputs, and hardware that can handle the sustained abuse of a full rally stage rather than the comparatively controlled environment of circuit driving.

Fitment for the Porsche 991 GT3 (2013-2019)

This listing covers the Porsche 991 GT3 (chassis code PO17-C) across the 991.1 and 991.2 generations built between 2013 and 2019, specifically in cars not fitted with the optional hydraulic front axle lift. The cancellation kit included with this fitment addresses the PASM electronic damping; confirm your car’s factory option list before ordering, as vehicles equipped with the hydraulic lift system require a separate fitment variant.
