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

Porsche’s PASM system on the 991 GT3 is genuinely capable in its adaptive range – but it makes decisions autonomously, shifts between modes based on sensor data, and cannot be locked to a single setting you have validated over a full day’s lapping. For owners who run the same circuit repeatedly and want to arrive with their setup confirmed in advance, that limitation matters. The XYZ Racing Super Sport coilovers address it directly: passive units replacing the PASM dampers, with a cancellation kit included so the car runs without fault codes or interference from the original control logic.

The 991 GT3 (chassis PO17-C) across the 2013 to 2019 production run spans two sub-generations – the 991.1 with its 3.8-litre unit and the 991.2’s 4.0-litre naturally aspirated flat-six – both sharing the same fundamental challenge of a rear-engine layout where roughly 62 per cent of the weight sits behind the axle centreline. The Super Sport’s 36-way adjustment range allows separate tuning conversations at each corner, which matters considerably more on this platform than it would on a conventional front-engined car.

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

Thirty-six damping positions cover the distance between a relaxed fast-road setting and a firm track configuration, with meaningful increments throughout. On the 991 GT3 – where rear-axle steering geometry is already working in the background at all speeds – the ability to adjust front and rear damping rates independently lets you influence the car’s rotation characteristics rather than accepting the balance Porsche calibrated for general-use owners. Ride height adjustment is independent of spring preload, so lowering the car for a circuit does not require compromising spring rate. The cancellation kit removes the PASM fault codes that would otherwise accompany passive dampers, ensuring the PDK and other chassis systems operate normally.

About the Super Sport coilover

The Super Sport sits in XYZ Racing’s range as their fast-road and weekend track offering – designed to absorb road surface variation without the harshness of a race-only unit, while delivering the adjustability a fixed-rate factory damper cannot provide. The 36-way damping adjustment is operated at the base of each unit, moving between full-soft and full-firm without dismantling the assembly. Threaded ride height collars allow stance changes across a meaningful range, independent of spring stiffness. The vendor specification confirms the system has been developed for weekend race use as well as regular road driving – a relevant credential on a car that many owners drive to the circuit, complete several sessions, and then drive home. No rebuild is required between road and track configurations; a screwdriver and a few minutes are sufficient to change modes.

Fitment for the Porsche 991 GT3 (without Hydraulic Lift System) (Cancellation Kit for Electronic Damping) (2013-2019)

This kit covers the Porsche 991 GT3 on chassis code PO17-C across the full production run from 2013 to 2019. It is specified for cars without the factory hydraulic lift system. The PASM cancellation kit is included and is essential for any 991 GT3 conversion to passive dampers – without it, the original control unit registers a fault condition that affects chassis system behaviour across the board.
