XYZ Racing Tarmac Rally Coilovers — BMW X4 G02 4WD 2018-2026

The X4 G02’s coupe-SUV proportions carry more mass higher off the road than any 3 Series or 4 Series wearing the same badge, and that extra leverage shows up exactly where a tarmac stage punishes it – mid-corner compressions, crested brows taken flat, and the transition from left-hander to right-hander with no time to settle. XYZ Racing’s Tarmac Rally coilover is built around that reality rather than around a track-day brief.

Where a circuit coilover chases the smoothest possible surface, this kit is calibrated for the opposite: broken tarmac, patched B-roads and stage surfaces that throw big, sudden inputs at the chassis rather than smooth, repeatable ones. On a 4WD X4 that’s carrying xDrive hardware and a raised centre of gravity, that distinction changes what the damper actually has to do lap to lap.

What this coilover brings to your 2018-2026 BMW X4

Fitted to a G02 X4, the immediate difference is how the car settles after a big hit rather than how it corners on a clean apex. The damping is set up to absorb a hard strike – a pothole, a broken edge, a crest landing – and control the rebound afterwards instead of letting the body pogo and unsettle the xDrive system’s ability to put power down out of the corner. That matters more on this car than on a lighter saloon, because the X4’s extra kerb weight and higher roll centre mean an uncontrolled rebound translates into a longer, harder-to-catch slide. The stiffer control also keeps the tyre’s contact patch loaded through the kind of mid-corner compression a tarmac stage throws up constantly, which is where traction is won or lost on a 4WD car that can otherwise mask a soft setup with all-wheel drive alone. Ride height stays adjustable so you can retain enough travel to survive a rough stage without bottoming the strut.

About the Tarmac Rally coilover

The Tarmac Rally range is XYZ Racing’s damper for exactly the discipline the name suggests: closed-road, sealed-stage tarmac rallying rather than circuit lapping. The valving is tuned to soak up the impact of an uneven road surface and control the shock body through big, sudden bumps rather than the smooth, repeated loading a track surface produces. That control is what keeps the tyre’s contact patch working under hard compression, which is where the stability and handling response come from once the car is loaded up mid-stage. The settings built into this kit come directly from XYZ Racing’s own experience running Tarmac Rally-specification dampers in competition, rather than being a detuned version of a circuit product. Construction follows XYZ’s coilover architecture, with height and damping adjustment retained so the setup can be leaned toward rough or smoother stages as the event demands.
