XYZ Racing Circuit Master Coilovers — Honda CIVIC EF CRX TWIN CAM (Rear EYE) 1989-1991

The EF-chassis CRX is a 900kg car with a double-wishbone setup at both ends and a twin-cam B-series under the bonnet – the platform that turned a generation of UK club racers into trail-braking believers. Get the damping right and an EF CRX rewards the driver more honestly than almost anything else on a UK circuit; get it wrong and the front end skates wide on entry and the rear EYE-beam axle starts hopping under load.

The XYZ Racing Circuit Master coilover is built for that second problem. This is the team’s top-tier circuit-spec damper, sized for sustained lap-time work on a 1989-1991 Civic EF CRX TWIN CAM (Rr EYE) chassis rather than a road compromise pretending to be one.

What this coilover does for your 1989-1991 Honda CIVIC EF CRX TWIN CAM (Rr EYE)

On a featherweight EF the Circuit Master gives you something a road-going coilover never can: a damping window wide enough to chase grip across a full session as the tyres heat-cycle. The 9720-position adjustment range means you can soften the front during the out-lap and stiffen it once the car is in temperature, instead of guessing once in the paddock and living with it. Three separate adjustment knobs split bump and rebound work, so you can dial the nose to bite into a slow hairpin without making the rear-EYE axle skip over kerb strips. For a twin-cam B16 EF CRX run hard, that translates into a flatter platform under trail-braking, more confidence to load the outside front, and a rear that follows the front instead of arguing with it.

About the Circuit Master coilover

The Circuit Master sits at the top of XYZ Racing’s competition range alongside their Racing Spec, Drift Spec and Tarmac Rally dampers. It is the design XYZ uses for international circuit work and the spec their teams take to long-format racing where the damper has to survive a full meeting. The 9720-way adjustment count comes from three independent knobs, each working a small oil orifice – the trade-off being that road potholes can produce a faint hydraulic note as oil moves through the restrictor passages. On a circuit surface that behaviour is invisible; the small-orifice design is what gives the damper its low-speed control through long, loaded corners. Construction and valving are sized for sustained heat soak rather than single hot laps, which is why XYZ position this as their endurance and lap-record damper rather than a sprint setup.
