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

The 991 GT3’s PASM setup gives you two settings: Normal, which errs toward road compliance, and Sport, which stiffens for circuit work. For owners who’ve found the gap between those two modes too broad to bridge sensibly, the XYZ Racing Street Advanced replaces the factory electronics with 720 manually selectable damping positions. Fitted without the hydraulic front lift system and supplied with the cancellation kit that prevents PASM fault codes from appearing on the dashboard, this coilover is designed to take over where the stock electronics leave off.

Porsche built the 991 GT3 to serve multiple masters – road legality, homologation requirements, everyday driveability. The Street Advanced for the 2013-2019 GT3 hands the suspension calibration back to the driver: ride height, spring preload, and damping rate are all adjustable by hand, without the car registering a fault.

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

Running a flat-six behind the rear axle gives the 991 GT3 a rear-weight bias that rewards precise suspension calibration. Replacing the binary PASM toggle with 720 increments of manual adjustment means you can run a softer road-biased setup during the week and firm the damping progressively for a circuit session, without swapping components or chasing corner weights between visits. Lowering the GT3 reduces its centre of gravity, sharpening turn-in response – particularly relevant on a car where the rear balance is already active and the spring rates are set from the factory for general road use rather than any specific circuit preference. The cancellation kit keeps the instrument cluster warning-free throughout.

About the Street Advanced coilover

The Street Advanced is XYZ Racing’s most widely specified coilover – developed over an extended period by the XYZ professional team and refined through use in competition at an international level before entering series production. Built for road use and track days, the 720-position damping range reflects that breadth: the lower settings give the compliance needed for public roads; the upper end firms up sufficiently for circuit sessions where managing the GT3’s rear-balance tendencies demands real control. XYZ describe the Street Advanced as the product of years of development and race-environment testing, and that’s evident in the damping character at both low-speed body movements and the higher-frequency inputs of broken circuit surfaces.

Fitment for the Porsche 991 GT3 (2013-2019)

This kit covers the 991-generation GT3 (chassis code PO17-C), spanning the full 2013-2019 production run across both the 991.1 (to 2016) and 991.2 (from 2017) builds. It is specified for cars not fitted with the hydraulic front lift system. The included electronic damping cancellation kit is required to suppress the PASM fault output that would otherwise trigger when the factory active dampers are removed.
