XYZ Racing Tarmac Rally Coilovers — BMW X5 G05 4WD (NON AIR STRUT) (Cancellation Kit for Electronic Damping) 2018-2026

The G05 X5 is a two-and-a-half-tonne SUV with a high centre of gravity, adaptive air-strut hardware from the factory, and a chassis tuned for comfort over composure. Throwing it down a closed tarmac stage exposes every one of those traits – body roll on turn-in, weight pitching forward under braking, and ECU faults the moment the standard electronic dampers see inputs they were never calibrated for. The XYZ Racing Tarmac Rally coilover for the BMW X5 G05 (BM111-C) addresses the chassis at its root: it replaces the air-strut system entirely and bundles the electronic damping cancellation kit so the car runs without dashboard errors.

This is the tarmac-stage spec, drawn from XYZ Racing’s rally programme. It is built to soak repeated kerb strikes and broken sealed surfaces while keeping the four contact patches loaded and predictable on a 4WD platform that wants to push wide if the front end goes light.

What this coilover does for your 2018-2026 BMW X5

On a 4WD car this heavy, the work the damper does between corners matters as much as what it does in them. The Tarmac Rally valving is set up to absorb sharp vertical inputs – drain covers, sunken patches, kerb edges – without unsettling the body or unloading a tyre at the wrong moment. You get a measurably flatter platform under braking, a front axle that holds its line into a long sweeper, and traction off the corner that the air-strut setup simply cannot replicate when the surface deteriorates.

Removing the air struts also removes a long-term failure point and gives you a height that stays where you set it. The cancellation kit keeps the dash clean and the adaptive-damping warning out of the cluster, so the car drives as a conventionally damped chassis should.

About the Tarmac Rally coilover

The Tarmac Rally series is engineered specifically to absorb the impact of uneven pavement and the jolt of larger bumps – the kind of inputs that arrive on a closed sealed stage and would skip a road-tuned damper across the surface. The valving suppresses shock through the body, keeps the tyre pressed into the road, and protects vehicle stability when the surface is anything but smooth. Every setting in this kit is drawn from XYZ Racing’s own tarmac rally competition experience, then translated to a road-legal coilover for owners who want that behaviour on a fast B-road as much as on a stage.

For the G05 application, the kit is supplied as a full replacement for the factory non-air-strut equivalent and includes the cancellation harness needed to silence the electronic damping controller. Construction follows the same monotube-derived philosophy XYZ uses across the rally range, with damping characteristics weighted toward absorption and traction rather than the harsh, low-amplitude control of a circuit setup.

Fitment for the BMW X5 (2018-2026)

This kit fits the G05 generation X5 in 4WD form, chassis code BM111-C, model years 2018 through 2026. It is the conversion spec – it replaces the factory non-air-strut suspension and includes the cancellation kit required for cars equipped with electronic adaptive damping. Confirm your car is the non-air-strut variant before ordering.
