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

The EF-generation Civic and CRX twin-cam with the rear fork mount is one of the lightest front-wheel-drive chassis Honda ever sold in the UK, and that featherweight kerb mass is exactly what makes spring and damper choice so consequential. Get it wrong and the car skips over mid-corner bumps; get it right and the EF rewards trail-braking and throttle-on rotation in a way modern hatches simply can’t.

The XYZ Racing Top Sport coilover is built for owners running these 1989-1991 EF Civics and CRXs on occasional track days while keeping the car usable on UK B-roads through the week. It is a circuit-leaning setup with enough compliance left in the damper curve to survive the realities of British tarmac.

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

Spring rates step up roughly 2 kg/mm over a typical street coilover, with damping wound 30-50% firmer than a fast-road tune. On an EF chassis that is light over the front axle and twitchy on lift, the firmer rates do two specific things: they cut the front-end dive that loads the outside tyre too early into a corner, and they keep the rear planted enough to let you carry mid-corner speed rather than washing wide. Body roll drops noticeably, ride height comes down for a lower roll centre, and the contact patch stays loaded under repeated kerb strikes. On track you get sharper turn-in and a chassis that tells you exactly where the grip is going; on the road you keep enough damper compliance to deal with broken surfaces without the car skipping off line.

About the Top Sport coilover

The Top Sport is XYZ Racing’s circuit-biased street coilover, drawn directly from the spring and damper curves the company runs in its own competition programmes. The damper tuning sits 30-50% firmer than a street setting, paired with spring rates around 2 kg/mm higher to absorb harder inputs without bottoming. The design priority is shock absorption over genuinely uneven pavement and big single hits – kerbs, expansion joints, mid-corner ridges – while suppressing body movement enough that the tyre traction stays consistent through a corner sequence. The settings are pulled from XYZ Racing’s own Top Sport racing experience, which means the rebound and compression balance is set for aggressive driving rather than comfort cruising. It suits track day work and committed road driving on a chassis like the EF, where the platform’s light weight means small damper changes show up clearly in how the car behaves.

Fitment for the Honda CIVIC EF CRX TWIN CAM (rr Fork) (1989-1991)

This kit is specified for the HN13 chassis, covering the 1989-1991 model run of the Civic EF and CRX twin-cam variants that use the rear fork mounting arrangement. The rear fork detail matters – the EF was sold in multiple rear-end configurations, and this coilover is cut specifically for the fork-type mount. Confirm your rear lower mount style before ordering.
