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

The 991 GT3’s rear-engine layout and rear-biased weight distribution are the defining characteristics of its handling character – the reason trail-braking into a corner loads the front so precisely, and the reason an overenthusiastic corner exit can unsettle the rear so sharply. Factory PASM handles the suspension’s adaptive work electronically, making decisions in milliseconds that suit most conditions most of the time. The XYZ Racing Super Sport coilover replaces that system with 36-way manual damping, shifting control back to the driver and allowing the chassis to be configured for specific circuits, tyre compounds, and varying road conditions.

This is XYZ Racing’s fast-road and weekend track specification – positioned for owners who use the 991 GT3 as it was designed to be used, alternating between circuit sessions and the road miles in between. The Super Sport is not an aggressive, comfort-destroying setup; the range of that 36-way adjuster is wide enough to substantially reduce road harshness without sacrificing the low, firm platform that the GT3’s steering precision depends upon.

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

Ride height adjustment lets you run the GT3 lower on circuit and raise the nose slightly for road sections where front splitter clearance matters – especially relevant on a car without the factory hydraulic lift system to manage that automatically. The 36-way damping range addresses both extremes of the GT3’s operating environment: the firmest settings suit smooth, fast circuit tarmac where the rear axle needs precise control through high-speed direction changes; the softer end takes the edge off the rough-surface feedback that transmits directly through the GT3’s already-firm chassis. Replacing PASM’s all-conditions electronic calibration with a manually set tune returns a more consistent, repeatable response through sustained fast corners.

About the Super Sport coilover

XYZ Racing developed the Super Sport to address a specific problem: dampers that reduce the impact of bumps and rough road surfaces without surrendering the adjustability that circuit use demands. The 36-way damping adjustment covers that full range – a single adjuster moves the setup from a supple, road-biased configuration to the kind of firm, planted tune that holds the GT3’s rear-biased balance through a fast, technical sequence. Ride height and damping are independently configurable, so preparing the car for a track day does not lock you into a harsh ride home. The Super Sport is rated for both regular road use and weekend racing, covering the spectrum that most 991 GT3 owners need across a full season of mixed use.

Fitment for the Porsche 991 GT3 (2013-2019)

This set is built for the Porsche 991 GT3 on chassis code PO17, covering the 2013 to 2019 model years and spanning both the 991.1 and 991.2 generations. This listing is specific to cars without the factory front hydraulic lift system; GT3 owners with the lift system fitted should confirm the correct part number before ordering, as the front strut configuration differs between the two variants.
