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

The 991 GT3 without the factory hydraulic lift system is, by definition, a more committed machine – owners who spec away the front-axle lift hardware are telling Porsche they are not worried about speed humps, and the cars tend to spend a great deal more time on circuit than on public roads. At that level of use, the factory suspension starts to show its compromises: damping calibrated around broad driver comfort, spring rates set to pass type-approval rather than to manage the specific aerodynamic and mechanical loading this chassis produces at circuit speeds.

That loading profile is genuinely unusual. The 991 GT3’s rear-engine balance, combined with the fixed wing’s rear-biased downforce and the GT3 Cup-derived double-wishbone front end, creates a chassis that rewards precise suspension tuning and responds sharply to imprecision under trail-braking. The XYZ Racing Racing Spec coilover is calibrated specifically for this kind of use, with settings drawn directly from WTCC and comparable race programmes rather than a simulated version of competition conditions.

What this coilover does for your 2013-2019 Porsche 991 GT3 (without Hydraulic Lift System)

On a 991 GT3 measured in lap sessions rather than road miles, the Racing Spec replaces factory damping with valving built for repeated, high-load circuit use. The rear-engine layout and fixed aerodynamic wing generate downforce and mechanical loading that vary sharply with speed and cornering load – conditions that compromise-oriented track-day setups manage broadly rather than precisely. Without the hydraulic lift hardware constraining front suspension packaging, spring rate and ride height work can go further than the lift-equipped variant allows. The result is a chassis that uses its inherent rear-engine rotation more controllably under braking, with more margin available into each corner entry.

About the Racing Spec coilover

The Racing Spec is XYZ Racing’s highest-specification coilover, built entirely around race use rather than any road and track balance. Where the brand’s other ranges carry a degree of daily-driveability in their calibration, the Racing Spec does not – its settings are derived from direct participation in competition events, including WTCC, meaning the valving reflects data collected under genuine race conditions. For 991 GT3 owners running the car in a significantly upgraded specification – extensive engine work, upgraded braking, aerodynamic packages, or circuit-specific geometry changes – XYZ Racing also produces custom shock absorbers built to a personal brief. Provide a full specification of every significant upgrade on the car and the circuit the car will run, and the dampers are built accordingly. This custom path makes the Racing Spec a credible option for A-class competition builds where a catalogue part is not close enough to the required specification.

Fitment for the Porsche 991 GT3 (without Hydraulic Lift System) (2013-2019)

This listing covers the Porsche 991 GT3 on chassis code PO17, production years 2013 to 2019, in the specific variant without the factory hydraulic front-axle lift system. Before ordering, confirm your car does not carry the front-axle lift hardware – the suspension packaging at the front differs between lift-equipped and non-lift 991 GT3 variants, and this coilover is engineered for the non-lift geometry.
