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

The HN13 CRX twin-cam is a 900kg featherweight with a rear-fork suspension layout that rewards stiffness more than almost any Civic that came after it. Get the geometry right and the car finds front-axle bite that modern hot hatches twice its weight can’t touch. Get it wrong and the chassis ties itself in knots over kerbs. The Circuit Master sits at the sharper end of the range – built specifically for the sustained lap-time work that a stripped EF CRX gets used for.

This is the coilover for owners who treat their 1989-1991 CRX as a circuit tool first and a road car second. It is not the right pick if you want a comfortable commuter setup. It is the right pick if your weekends involve timing transponders.

What this coilover does for your 1989-1991 Honda Civic EF CRX

On a chassis as light as the HN13, damping resolution matters more than spring rate alone. The Circuit Master gives you 9720 individual adjustment combinations across its three knobs, which means you can separate bump and rebound behaviour over the front rear-fork geometry until the car stops loading the outside tyre too aggressively on turn-in. Expect noticeably calmer mid-corner attitude through long, loaded bends – the kind of place a soft EF gets nervous. Brake stability into hairpins improves once you stiffen low-speed compression at the front. Kerb-strike behaviour stays composed because the damper handles the spike rather than transmitting it to the steering rack.

About the Circuit Master coilover

The Circuit Master is XYZ Racing’s competition-spec damper, sitting in the same family as their Racing Spec, Drift Spec and Tarmac Rally builds. The headline figure is 9720 ways of adjustment, delivered through three independent knobs – separating low and high-speed damping behaviour in a way the entry-level kits cannot. The design has been run by XYZ racing teams on circuits internationally and refined through long-duration testing. One honest note from the engineering brief: the small-oil-hole design that gives the damper its precision on smooth tarmac will produce a faint hydraulic noise when forced over large bumps. That is the trade-off for circuit-grade control, and it is the reason this damper is specified for track surfaces rather than broken B-roads.

Fitment for the Honda Civic EF CRX TWIN CAM (Rr Fork) (1989-1991)

This kit is built for the HN13 chassis Civic CRX twin-cam with the rear-fork suspension layout, covering the 1989 to 1991 production span. The rear-fork variant matters – running coilovers spec’d for the non-fork EF rear end will not give you correct geometry on this car.
