XYZ Racing Super Sport Coilovers — Honda CIVIC EF CRX SINGLE CAM (Rear FORK) 1989-1991

The rear-fork EF CRX is one of the lightest hot Hondas Honda ever sold in Europe, and three decades on the original twin-wishbone geometry still rewards a driver who feeds it properly – but only if the dampers can keep the unsprung mass under control. Tired OEM struts let the nose dive on turn-in and the inside rear go light far too early, which is exactly the failure mode the Super Sport coilover is built to fix.

For a single-cam D-series EF CRX used as a weekend toy and occasional trackday car, this is the kit that lets you lower the ride height without ruining it on a Cotswold B-road. The 36-way damping range covers everything from a road-biased setting on the way to Castle Combe to a firmer click for the sessions themselves.

What this coilover does for your 1989-1991 Honda Civic EF CRX Single CAM (rr Fork)

Dialled correctly, the Super Sport tightens the EF chassis without making it brittle. The 36-way bump and rebound adjustment lets you control the front-end dive that exposes the CRX’s short wheelbase under braking, and the height adjustment closes the arch gap that all these cars now wear. On the rear fork-style strut, sharper damping pulls the inside wheel back into the road during fast direction changes – the rear-lift moment that defines an EF on a tight circuit. Spring rate and valving are matched for road use first, so the kerbs you have to drive over to get home from the track don’t punish you the next morning. Stance, turn-in bite and mid-corner composure all move in the same direction without forcing a compromise on daily driveability.

About the Super Sport coilover

The Super Sport is XYZ Racing’s fast-road damper, engineered to absorb broken UK tarmac while still holding a corner under load. Construction is a height-adjustable coilover unit with 36 clicks of damping adjustment, letting the driver tune compression and rebound behaviour to suit the surface and the session. XYZ position the Super Sport as the dual-purpose kit in the range – the one designed to take the discomfort out of bumps and rough roads while still being suitable for weekend racing. In other words: a single set of dampers configured for the road on Friday and the circuit on Saturday, without swapping springs or rebuilding the car between the two. It sits below the Top Sport in the XYZ hierarchy on track focus, but above any passive lowering kit on adjustability and rebuild potential.
