XYZ Racing Gravel Rally Coilovers — Porsche 991 GT3 (without hydraulic lift system) 2013-2019

The 991 GT3’s rear-engined, rear-wheel-drive layout was conceived for tarmac circuits and fast road – where the flat-six’s mass aft of the rear axle can be exploited by a driver who understands the car’s tendency to pivot around that engine on corner entry. Transplant that platform onto a gravel stage and the physics change entirely: the pendulum behaviour of the rear-mounted engine demands a damper engineered around loose, unpredictable surfaces, not a tarmac-spec strut calibrated for kerb strikes.

The XYZ Racing Gravel Rally coilover addresses exactly that demand for the Porsche 991 GT3 in 2013-2019 form. Built on an inverted tube architecture with the long stroke and extended spring travel needed for sandstone, silt, and snow stages, it gives the 991’s distinctive weight distribution a controlled response when the ground drops away at speed or the surface changes composition mid-corner.

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

The GT3’s factory suspension is calibrated for smooth tarmac; on loose ground it exhausts its stroke quickly, and what felt like responsive body control on a circuit translates to a car that deflects and skips over ruts. The Gravel Rally unit’s extended stroke absorbs the repeated shock inputs of competitive gravel use, preserving traction and directional stability through rough sections that would unsettle a tarmac-modified setup.

Structurally, the inverted tube design – with the larger-diameter outer tube acting as the sliding element – resists the lateral loads that a rear-engined car generates when pivoting hard over the rear axle on loose surfaces. Spring rates have been validated by XYZ Racing’s rally team against real competition conditions, so what you are fitting is a tested, confirmed quantity rather than a theoretical rate lifted from a spreadsheet. Without the factory hydraulic lift system, the 991 GT3 has no adaptive-height assistance from the OEM, which makes the Gravel Rally unit the sole mechanism for managing ride height and ground clearance across the variable terrain that stage events produce.

About the Gravel Rally coilover

The Gravel Rally line is built specifically for rally and rallycross competition – disciplines where road surfaces impose shock loadings that tarmac-spec dampers handle poorly. The inverted monotube construction concentrates lateral stiffness through the strut body, resisting the extreme cornering G-forces that arrive at speed on sandstone, snow, or silt.

Long travel springs work alongside the extended stroke to manage chassis vibration and control the abrupt vertical forces generated when a car strikes broken ground at pace. All spring rates in the Gravel Rally range have been tested by XYZ Racing’s own rally team – a standard applied across the programme and matched to the specific chassis dimensions and geometry of each application. The 991 GT3 specification is designed for aggressive commitment on stage, not a road kit with longer springs added as a rough approximation of rally-spec travel.

Fitment for the Porsche 991 GT3 (2013-2019)

This kit is calibrated for the Porsche 991 GT3 (chassis code PO17) from 2013 through to 2019, covering both 991.1 and 991.2 generations of the model. The application is specific to cars without the factory hydraulic lift system; the front-axle geometry this unit is built around is the non-HLS standard configuration. Confirm your car’s build specification in the configurator before selecting.
