XYZ Racing Circuit Master Coilovers — Infiniti G20 P10 1990-1997

The P10 G20 is a strange beast to bring to a UK circuit in 2026 – a JDM-engineered Primera P10 sold as a near-luxury saloon in North America, running the SR20DE up front, a multi-link beam at the rear, and a kerb weight that flatters its 140bhp output. Owners who still campaign one know the chassis has more in it than the soft factory damping ever revealed. The Circuit Master coilover is the kit you fit when you have stopped pretending this is a comfortable commuter and started treating the P10 as the lightweight front-driver it always wanted to be.

Where the Top Sport and Super Sport ranges hedge toward road usability, Circuit Master is the spec XYZ Racing builds for sustained circuit lap-time work. On a P10 G20 that means controlling the nose under heavy braking into a hairpin, keeping the inside rear loaded enough to put SR20 torque down out of the corner, and resisting the slow heat-soaked fade that destroys lap consistency in cheaper damping.

What this coilover does for your 1990-1997 Infiniti G20 P10

Fit Circuit Master to a P10 and the first thing you feel is platform stiffness – the chassis stops wallowing mid-corner and starts pivoting around the driver. The 9720 individual adjustment combinations are not a marketing number; they let you separate low-speed body control from high-speed bump compliance, which matters on British circuits where Silverstone’s kerbs and Cadwell’s elevation changes ask very different things of the same kit. Front-end bite under trail-braking improves immediately, the rear beam loads more predictably under throttle, and the front-drive understeer that defines a stock G20 P10 becomes something you can dial out rather than drive around. Spring rates suited to circuit work also drop the ride height enough to recover a useful chunk of front camber from the P10’s strut geometry.

About the Circuit Master coilover

Circuit Master sits at the top of XYZ Racing’s competition-focused range, alongside the Racing Spec, Drift Spec and Tarmac Rally builds. Three separate adjustment knobs handle the full 9720-way damping matrix, and the design has been validated by XYZ race teams on international circuits over years of testing. One characteristic worth knowing before you fit it: the small-passage oil-hole design that gives Circuit Master its sharp response over circuit-grade surfaces will produce a faint audible note when the damper is hammered over genuinely large road bumps. That is the dampers behaving as designed, not a fault – this is a kit built for circuit tarmac, not B-road potholes. Construction targets the kind of heat cycling and repeat-session abuse that destroys budget coilovers within a season of serious track use.

Fitment for the Infiniti G20 P10 (1990-1997)

This kit is built for the P10-chassis G20 sold from 1990 through 1997, covering the full first-generation run before the P11 replaced it. Chassis code P10 – the Primera-derived platform – is the confirmed fitment. Confirm your year and trim against the configurator before ordering.
