XYZ Racing Circuit Master Coilovers — Porsche 992 GT3 (without hydraulic lift system) 2021-2026

The 4.0-litre flat-six sitting behind the rear axle defines both the appeal and the challenge of the 992 GT3 on circuit. Under hard braking, mass transfers forward, the rear progressively unloads, and the margin between a car that rotates willingly and one that steps out without warning compresses to nothing. That balance is what damper tuning addresses – and factory PASM, however sophisticated, makes its decisions autonomously. At Silverstone or Spa, you need to make them yourself.

The Circuit Master coilover is XYZ Racing’s answer for sustained circuit lap-time work. It sits at the top of the competition range, sharing its development lineage with the Racing Spec, Drift Spec, and Tarmac Rally variants, and it is designed entirely around circuit use – not the occasional fast-road blast.

What this coilover does for your 2021-2026 Porsche 992 GT3 (without Hydraulic Lift System)

With 9,720 adjustment combinations across three independent knobs, the Circuit Master gives you direct authority over how the 992’s rear-biased platform behaves through every phase of a lap. Ride height adjustment lowers the centre of gravity further than the factory system permits, reducing body roll through the sustained lateral loading the GT3’s wide front tyres generate in fast corners. The ability to fine-tune the front-rear compression and rebound relationship means you can address the rear’s tendency to unload under braking, stiffen the rear relative to the front on a high-grip surface, or soften the compression side for a circuit with rougher asphalt that punishes a rigid set-up. On a car whose chassis is already near the limit of what factory calibration can optimise, that granularity is meaningful.

About the Circuit Master coilover

The Circuit Master sits at the competition end of the XYZ Racing coilover range, developed and validated through XYZ Racing teams running on circuits worldwide. The three-knob system – compression, rebound, and ride height each adjusted independently – produces 9,720 distinct damper configurations, enough granularity to respond to different tyre compounds, changing track conditions across a session, or the specific surface character of each circuit. The small oil passage design through the damper body controls flow rate during large bump events, keeping the damper stable through the compression spikes that circuit kerbs generate; it is worth noting that this architecture can produce a small amount of noise over significant bumps, which is inherent to the oil passage design and not a fault. The Circuit Master is built specifically for circuit conditions – consistent surfaces, defined kerb profiles – rather than the unpredictable inputs of public roads.

Fitment for the Porsche 992 GT3 (without Hydraulic Lift System) (2021-2026)

This coilover is developed for the 992-generation GT3 on chassis code PO25, covering model years 2021 to 2026. It applies specifically to cars without the factory hydraulic nose-lift option; the lift system alters front suspension geometry and a separate fitment is required if yours is so equipped. Confirm your build specification or original order documentation before purchasing.
