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

The 991 GT3’s double-wishbone front suspension – a deliberate departure from the MacPherson struts found on every other 991 – transformed what a road-registered GT3 could do dynamically. But it also means the factory PASM setup is a genuine engineering compromise: Porsche had to make one calibration serve both the Nürburgring and a Tuesday morning commute, and that tension is felt every time conditions shift.

The XYZ Racing Street Advanced coilover for the 991 GT3 (without hydraulic lift system) gives owners the hardware to unpick that compromise on their own terms. With 720 ways of damping adjustment across the range, it covers comfortable fast-road use and focused track-day sessions from the same set of dampers – no swapping, no separate track setup stored in the garage.

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

The rear-engine layout means the rear dampers carry the majority of the car’s dynamic load under hard use. Get the rebound setting wrong and the 991 GT3 feels unsettled through fast direction changes; oversprung and you trade mechanical grip for a car that skates over the surface on bumpy circuits. The Street Advanced’s 720-way range gives you the granularity to dial the rear to the surface rather than the other way around.

Running without the factory hydraulic nose-lift also means you’re already making manual ride-height decisions. A full coilover system lets you lower the front to a sensible road stance without compromising the geometry that the wide-track double-wishbone front end requires to work correctly – suspension travel is available, and you configure it rather than accepting whatever Porsche shipped it with.

About the Street Advanced coilover

XYZ Racing’s Street Advanced is the brand’s most developed road-oriented product – the result of years of refinement by their professional engineering team, with performance validated through competition in races worldwide before the design reached the road-use market. The headline specification is 720-way damping adjustment: a range wide enough to cover everything from a comfortable ride on imperfect UK roads to a stiffer, body-motion-controlled setup for a track day, all without changing hardware.

The Street Advanced is built for drivers who want active control over their car’s behaviour rather than a fixed factory compromise. Both use cases – relaxed road driving and focused circuit use – are addressed by the same kit, which makes it a logical single-purchase solution for a GT3 that genuinely sees both environments.

Fitment for the Porsche 991 GT3 (2013-2019)

This kit covers the Porsche 991 GT3 without the factory hydraulic front-axle lift system, across the full production span from 2013 to 2019 – taking in both the 991.1 and 991.2 generations. Chassis code: PO17. Before ordering, confirm your car’s front suspension specification: 991 GT3 models fitted with the optional hydraulic nose-lift system are a different configuration and require a separate fitment.
