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

The 991 GT3 RS is Porsche’s most extreme naturally aspirated 911 – and an unusual choice for competitive drifting. Its rear-engine layout, with the 4.0-litre flat-six sitting behind the rear axle, creates a rear-biased weight distribution that competition drifters can exploit, but only once the suspension is configured to manage that rearward mass under high-angle, high-speed conditions rather than maximum lateral grip.

Fitting any aftermarket coilover to the 991 GT3 RS means bypassing PASM, Porsche’s electronic damping management system. This kit includes the cancellation interface to accomplish that cleanly, replacing adaptive control with a fully mechanical, adjustable platform built for drift competition from the ground up.

What this coilover does for your 2016-2026 Porsche 991 GT3 RS

Lowering the 991 GT3 RS through the adjustable height perches reduces the centre of gravity, reshaping how the rear-heavy weight distributes during sustained slides. Body roll through extended high-angle runs becomes more controlled – the chassis stays readable rather than lurching between positions mid-slide. With PASM removed from the equation, damping response is fixed and consistent, giving the driver reliable tyre feedback on every run rather than the variation an adaptive system introduces. Bump stroke has been specifically calibrated for drift technique, allowing geometry changes to happen gradually and linearly when the car is held at angle rather than spiking through the inputs that competition drifting generates.

About the Drift Spec coilover

The Drift Spec is XYZ Racing’s dedicated competition drift coilover, built around the specific mechanical demands of high-speed, high-angle circuit drifting. Where a road or track-day coilover manages body motion in service of grip and lap time, this kit prioritises body stabilisation – keeping the chassis consistent and legible when the driver is working at extreme slip angles in full competition conditions. Ride height adjustment and optimised bump stroke work in combination: setting the ride height correctly changes the contact patch loading geometry, while the calibrated bump stroke ensures the suspension behaves in a controlled, predictable manner rather than hunting through the abrupt inputs that drift technique demands. The kit was designed specifically for drift race use, with the stated aim of giving competitors the ability to set and hold a repeatable angle at speed.

Fitment for the Porsche 991 GT3 RS (2016-2026)

This kit fits the Porsche 991 GT3 RS on chassis code PO13-C, covering the 2016 to 2026 production window. It is specified for cars not fitted with Porsche’s optional Hydraulic Lift System – owners with HLS should confirm the correct variant before ordering. The PASM cancellation interface is included in the kit, allowing a clean installation without generating persistent fault codes from the electronic damping management system.
