XYZ Racing Circuit Master Coilovers — Citroen ZX 1991-1998

The ZX is one of the great forgotten chassis of the 1990s – a lightweight French hatch with a passive rear-steer axle that rotates with an honesty most modern hot hatches have engineered out. The Circuit Master is the right coilover for an owner who has already discovered what this car does on a circuit and now wants to make it repeatable across a full session.

For sustained lap-time work in a ZX, you need a damper that holds composure when the oil is hot and the tyres are past their first heat cycle. The Circuit Master is built for exactly that window, and it is the kit XYZ Racing’s own competition customers run when the answer matters.

What this coilover does for your 1991-1998 Citroen ZX

On a ZX, the gains land in two places. First, body control on turn-in: the front end stops dipping under trail-braking, so the passive rear axle has a stable platform to work against, and the car starts rotating on the brake pedal the way it was always trying to. Second, repeatability: where a softer kit goes off after four or five hot laps as the oil thins, the Circuit Master’s monotube layout shrugs that off and gives you the same lap on lap eight that you had on lap two.

The 3-way knob layout lets you separate bump from rebound, so you can stiffen rebound to control the ZX’s tendency to unload the inside rear on long corners without making the kerb-strikes brutal. Ride height drops are corner-balanceable too, which matters on a car this light – a few millimetres of cross-weight changes the balance noticeably.

About the Circuit Master coilover

The Circuit Master sits at the competition end of the XYZ Racing range, shared in spec philosophy with their Racing Spec, Drift Spec and Tarmac Rally kits. The headline figure is 9,720 distinct damping settings, accessed through three independent adjustment knobs – high-speed bump, low-speed bump and rebound – so the damper response can be tuned to a specific circuit’s mix of kerbs, sweepers and braking zones rather than compromised across all three.

Construction is competition-grade monotube with a high oil capacity to resist fade during back-to-back sessions. The development brief is unambiguous: this kit has been tested by XYZ Racing teams worldwide on international circuits and refined over long-run pace, not single hot-lap pulls. One honest note from the manufacturer – the small-bore oil passages that give the Circuit Master its precision can produce a faint hydraulic noise over sharp road bumps. That is the trade for a damper built to live on a track surface, where ride harshness over potholes is not part of the brief.

Fitment for the Citroen ZX (1991-1998)

This kit is built for the CI06 chassis ZX across the full 1991-1998 production run, covering hatchback and Volcane variants on the same platform. Spring rates and pickup points are set up for the ZX’s strut-front, passive-rear-steer torsion-beam layout – confirm your trim at checkout so the spring pairing is matched to your kerb weight.
