XYZ Racing Racing Spec Coilovers — Porsche 991 GT3 RS (without hydraulic lift system) (Cancellation Kit for Electronic Damping) 2016-2026

The 991 GT3 RS arrived from the factory as close to a racing car as Porsche’s regulations allowed – active PASM dampers calibrated to manage the rear-engine weight bias, a 4.0-litre flat-six spinning to 9,000rpm, and suspension geometry that asked serious questions of the driver. For circuit use beyond occasional track days, the factory electronic damping becomes a constraint rather than an aid: its response maps are fixed, its curves predetermined, and it offers no mechanical route to the fine adjustments that separate one lap time from the next.

This XYZ Racing Racing Spec coilover is designed for 991 GT3 RS owners running without the factory hydraulic front-axle lift system. The kit includes a cancellation unit for the electronic damping control, replacing the PASM setup with a mechanically adjustable coilover that puts damping decisions in your hands rather than the car’s software.

What this coilover does for your 2016-2026 Porsche 991 GT3 RS (without Hydraulic Lift System) (Cancellation Kit for Electronic Damping)

Bypassing the factory PASM transforms the 991 GT3 RS from a car that interprets your inputs to one that simply executes them. With the electronic damping removed from the equation, spring rate and damping adjustments are direct – you can stiffen the rear to manage the lift-off oversteer tendencies inherent to the 911’s rear-weight bias, or work on front-axle compliance to redistribute load during trail-braking. Ride height adjustment lets you run the 991 GT3 RS at the geometry the rear-engine layout rewards on circuit, free of the compromises the factory system maintains for road use. Track-session feedback translates immediately into mechanical change.

About the Racing Spec coilover

The Racing Spec is XYZ Racing’s damper range for track and time-attack use, with settings developed from direct participation in competition including the World Touring Car Championship. Where the brand’s road-biased ranges span a comfort-to-sport window, the Racing Spec’s calibration sits entirely within circuit territory – compression and rebound settings are built for sustained on-circuit use rather than day-to-day driveability. For owners running the 991 GT3 RS with more aggressive upgrades that fall outside standard catalogue range – or targeting a specific circuit – XYZ Racing offer custom-built shock absorbers built to match. Supply details of your full modified specification and the circuit you intend to run, and the team can engineer a shock absorber to that exact brief. The option exists for cars with modifications equivalent to factory racing vehicles or A-class racing specifications; it is a genuine engineering process, not a footnote.

Fitment for the Porsche 991 GT3 RS (without Hydraulic Lift System) (Cancellation Kit for Electronic Damping) (2016-2026)

Listed under chassis code PO13-C, this kit covers the 991 GT3 RS from 2016 to 2026 in the specification without the factory hydraulic front-axle lift system. The electronic damping cancellation unit is included as part of the fitment, making this a complete mechanical replacement for the factory PASM setup. Confirm your build is the non-FLHS specification before ordering.
