XYZ Racing Tarmac Rally Coilovers — BMW 5 SERIES G30 (Cancellation Kit for Electronic Damping) 2017-2026

The G30 5 Series was never meant to attack a sealed special stage. It is a 1.6-tonne executive saloon with electronic dampers that prioritise wafting over wheel control, and the moment you point one at a tightening third-gear corner with broken tarmac on the apex, the standard setup goes vague – body float on compression, a slow recovery on rebound, and an electronic damper map that fights every input you give it.

The XYZ Racing Tarmac Rally coilover for the BMW 5 Series G30 deletes that compromise. It is a full mechanical replacement with the cancellation kit needed to silence the factory electronic damping module, so the chassis no longer has a software layer second-guessing your damper settings on stage.

What this coilover does for your 2017-2026 BMW 5 Series G30

Big-bump absorption is the headline. The damper valving is set up to soak the worst of broken UK tarmac – the kind of mid-corner ridges and compressions that throw a standard G30 off line – without packing down on the next hit. That keeps the contact patch loaded when you need traction, rather than letting the tyre skip into understeer.

You also get back the steering response that the OEM EDC system blunts. With the electronics cancelled and a fixed mechanical damper in their place, inputs land cleanly: turn-in is sharper, the nose stops washing under trail braking, and the rear axle stops the late-rotation surprise the G30 can throw on a lifted throttle. Ride height drops to a sensible stage-rally stance, with corner-balanceable spring perches for setup work between service.

About the Tarmac Rally coilover

This is a dedicated tarmac-rally damper, not a fast-road kit rebadged. The valving is drawn directly from XYZ Racing’s tarmac-stage programme, where the brief is impact absorption on uneven surfaces without losing body control between hits. The damper is designed to swallow a big compression – a kerb, a crown, a patched repair – and recover quickly enough to handle the next one without bottoming or running out of stroke.

The G30 application ships with the cancellation kit required for the car’s electronic damping system, so the factory EDC warning is suppressed and the new damper runs on its own mechanical settings. Construction is built around the load case of a heavy saloon being driven hard on imperfect surfaces, with spring rates and damper curves matched to the chassis weight rather than a generic one-size-fits-all map. Tyre traction is the goal – keeping rubber in contact with the road when the road is doing its best to throw it off.

Fitment for the BMW 5 Series (2017-2026)

Direct fit for the BMW 5 Series G30 chassis (XYZ chassis code BM78-C), model years 2017 to 2026. The kit includes the cancellation harness required for the factory electronic damping module, so EDC-equipped cars do not need any additional dealer coding to clear the dashboard warning.
