XYZ Racing Tarmac Rally Coilovers — BYD F0 2008-2026

The Byd F0 is an unlikely rally weapon – a 1.0-litre city hatch on a short wheelbase that punches well above its kerb weight when the surface gets broken. On a sealed special stage, what wins time is not power but the ability to keep four tyres loaded through compressions, kerb-strikes and mid-corner ridges that would unsettle a softer setup. That is the brief these XYZ Racing Tarmac Rally coilovers were built for.

This is the rally-spec damper for the F0 platform – tuned to soak up the abuse of a stage surface while keeping the body settled enough to carry speed through fast sweepers. The valving comes straight from XYZ Racing’s own tarmac rally programme, which is where these settings were proven before they reached the catalogue.

What this coilover does for your 2008-2026 Byd F0

On a stage with mid-corner bumps and patched tarmac, the F0’s light front end has a tendency to skip and lose contact under load. The Tarmac Rally damper is valved to absorb that shock through the body rather than transmit it into a sudden weight transfer, so the front tyres stay planted and your line stays where you put it. Across kerbs and compressions, the damper takes the hit and recovers fast enough to load the next corner cleanly.

The result on the F0 is a car that feels heavier and more deliberate than its 800-odd kilos suggest – more traction out of slow corners, more confidence to commit to fast ones, and a markedly calmer body over surfaces that would normally have a city hatch hopping wide. You also gain ride-height adjustment to drop the stance for tarmac work without sacrificing the travel the damper needs to do its job.

About the Tarmac Rally coilover

This is a dedicated tarmac-rally damper, not a road coilover with stiffer springs. The construction and valving are built around impact absorption – the ability to take a big single hit, suppress the resulting body movement, and put the tyre back on the ground with grip intact. That is a different engineering target to a circuit coilover, where the surface is predictable and the priority is platform stability under steady-state load.

The valving is derived directly from XYZ Racing’s tarmac rally competition programme. Every setting in this kit – bump, rebound, spring rate selection – was developed and signed off on real sealed stages, not on a dyno bench. For an F0 owner running tarmac events or fast B-roads with broken surfaces, that competition lineage is the difference between a coilover that survives the abuse and one that uses it.

Fitment for the Byd F0 (2008-2026)

This kit is built for the Byd F0 city hatchback on the BY01 chassis code, covering the full 2008 to 2026 production run. Mounting points and stroke length are matched to the F0’s MacPherson front and torsion-beam rear layout – no fabrication or modification needed for installation.
