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

The EF-chassis CRX is a sub-900kg featherweight with rear trailing arms and a front double-wishbone setup that was already half a track car when it left Suzuka in 1989. What it lacks is damping that can keep up with a stripped, lightened, modded example on a B-road or a Cadwell lap – the factory shocks were valved for a daily that no longer exists. The XYZ Racing Top Sport coilover for the Honda Civic EF CRX Single Cam (Rr Fork) 1989-1991 is built to fix exactly that.

Top Sport is XYZ’s circuit-leaning kit for owners who still drive to the track. It runs roughly 30-50% more damping and around 2kg/mm more spring rate than a street tune, calibrated to the rear-fork lower mount specific to this generation of EF rear end so the geometry stays correct on installation.

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

The CRX rewards quick hands and a stable platform, and the firmer spring-and-damper pairing here gives it both. Across patched UK tarmac the increased damping force absorbs sharp inputs that would otherwise pitch this short-wheelbase car into wheelspin out of a second-gear corner, holding the tyre against the road rather than letting it skip. Body roll drops, turn-in sharpens, and the rear stops floating over mid-corner crests – the failure mode that makes a stock EF feel nervous when you start pushing.

For trail-braking into a hairpin the front end stays loaded longer, so you can rotate on the brakes without the rear stepping out unprompted. Ride height is adjustable for stance and corner-weighting, and the rear fork-style lower mount drops straight into the OE pickup without bracket fabrication. It is firm – this is a track-biased setup – but well within the range a stripped EF/CRX owner runs daily.

About the Top Sport coilover

Top Sport is XYZ Racing’s circuit-day specification, sitting above the street range on damping force and spring rate. The valving is derived from XYZ’s own racing programme and runs roughly 30-50% more damping than a street setting, paired with springs around 2kg/mm stiffer than a fast-road tune. The intent is to suppress body movement under hard cornering, big kerb strikes and uneven track surfaces while keeping enough compliance to drive the car to the circuit and home again.

Construction is full-coilover with adjustable ride height and damper adjustment, so the same kit covers a track session, a road drive and a corner-weight setup on the same weekend. The Honda Civic EF CRX Single Cam application uses the rear fork lower mount specific to the HN12 platform. Top Sport is the right pick when Super Sport street feels under-damped on track but a fully circuit-only kit would be intolerable on the road.

Fitment for the Honda CIVIC EF CRX Single Cam (Rr Fork) (1989-1991)

This kit is fit-specific to the EF-generation Civic CRX Single Cam, chassis HN12, model years 1989-1991, with the rear-fork lower mount geometry. It bolts to the factory pickup points front and rear with no bracket modification, and replaces the OE strut and shock assemblies as a complete unit.
