XYZ Racing Tarmac Rally Coilovers — BYD DOLPHIN 2021-2026

The BY04 Dolphin is an unusual base for a tarmac rally build – a 1.5-tonne front-wheel-drive EV hatch with instant torque, a low-slung skateboard battery, and a centre of gravity most rally cars would envy. What it lacks is damping intelligent enough to cope with the broken cambers, mid-corner crests and patched-asphalt special stages that define sealed-surface rallying. That is what this kit exists to fix.

The XYZ Racing Tarmac Rally coilover for the Byd 海豚 Dolphin 2021-2026 is a stage-specification damper built around the realities of competition-grade tarmac work. It takes a battery-heavy front-drive chassis and gives it the wheel control to hook up traction out of hairpins and the body discipline to stay flat over yumps and crested transitions.

What this coilover does for your 2021-2026 Byd Dolphin Dolphin

Battery weight is the Dolphin’s defining handling trait, and these coilovers are tuned around it. The damper valving is calibrated to absorb the impact of broken pavement without unloading the contact patch, so the front tyres keep hooking up under power even when the surface goes against you. Body movement is suppressed through fast transitions, which is where a heavy EV hatch normally goes vague. Tyre traction climbs noticeably on uneven sections, particularly the patched and ridged surfaces typical of UK closed-road events. The result is a Dolphin that feels planted at corner-entry speeds it has no business carrying on standard suspension, with the stability you need to commit through a flat-out kink without lifting.

About the Tarmac Rally coilover

The Tarmac Rally is a discipline-specific damper, not a fast-road kit with stiffer springs. The valving and spring rates are drawn directly from XYZ Racing’s own tarmac rally programme – this is the setup logic the firm runs on its competition cars, not a desk-built calibration. The damping philosophy prioritises shock absorption over uneven pavement: the unit takes a big hit, dissipates it without packing down, and returns the wheel to the road before the next input. That matters on sealed stages where a single missed bump compromises three corners of pace. Construction is built for the abuse of stage-spec use, with the heat capacity and seal integrity to survive a competitive day’s running. The settings are tuned to keep the body composed across big compressions while letting the wheel work the surface at high frequency.
