XYZ Racing Tarmac Rally Coilovers — Honda CIVIC EF CRX SINGLE CAM (Rear EYE) 1989-1991

The EF-generation CRX is a lightweight, short-wheelbase chassis that responds to suspension changes more vividly than almost anything else of its era – and on a broken tarmac stage that sensitivity becomes the entire conversation. The Tarmac Rally coilover is built for that exact job: keeping a 900-kilo Honda planted when the surface stops being a surface and starts being a series of compressions, crests and mid-corner kerbs.

For a single-cam EF CRX running rear eye-mount geometry, the priority is shock absorption that doesn’t blow through its travel on a heavy hit, then recovers fast enough to load the next apex. This is a closed-course rally damper, not a fast-road compromise, and it reads accordingly.

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

On a stage, the EF chassis lives or dies on traction out of slow, lumpy second-gear corners – the kind where a stiff circuit setup skips the inside rear and bleeds the run-up to the next bend. The Tarmac Rally damping is tuned to swallow the big single hits without packing down, so the contact patch stays loaded through compressions instead of unweighting over them.

That translates to a CRX you can actually lean on mid-corner: more confidence to commit early, less correction needed when the road kicks back. The rear eye-mount geometry on this car means the damper is taking a lot of the suspension’s working load directly, so a unit engineered to absorb impact – rather than just control body roll – is the right answer for sealed-stage tarmac use.

About the Tarmac Rally coilover

The Tarmac Rally damper is a closed-course tarmac specialist, developed out of XYZ Racing’s tarmac rally programme rather than adapted from a circuit base. The brief is impact absorption first: when the CRX hits a broken kerb or a compression mid-stage, the damper has to soak the jolt without transferring it into chassis pitch or wheel hop.

Suppressing that shock through the body is what keeps the tyre loaded, and a loaded tyre is what gives you traction on a surface that punishes anything else. The settings supplied are pulled directly from XYZ Racing’s own tarmac rally testing – shim stacks, valving and ride-height baselines that have been signed off on real sealed stages, not extrapolated from a road remit.

This is not a coilover that pretends to be friendly on a commute. It is a stage damper that happens to bolt to an EF Civic, and the geometry, valving and travel are set for that purpose.

Fitment for the Honda CIVIC EF CRX SINGLE CAM (Rr EYE) (1989-1991)

Built specifically for the EF-chassis CRX (chassis code HN10) single-cam variant running rear eye-mount lower shock geometry, 1989 to 1991. Because EF-era Civics and CRXs varied lower-mount type between markets and years, confirm your rear damper mounting is eye-type before ordering – the bolt-through CRX rear setup is what this kit is valved and dimensioned for.
