XYZ Racing Tarmac Rally Coilovers — BMW X3 F25 4WD 2010-2017

The F25 X3’s raised ride height and xDrive-driven mass shift more load into the suspension than a standard 3-series ever sees, and that’s exactly the terrain the Tarmac Rally coilover for this chassis is built for: sealed-stage rally work where the surface changes camber and grip level mid-corner without warning. Where a road-biased set-up would let the X3’s taller body roll and unsettle across a compression, this kit keeps the tyre loaded through the transition instead of letting it skip.

For crews running the BM79 X3 on closed tarmac stages, that means less time spent managing a wallowing SUV chassis and more time putting power down through all four corners. The kit is built around XYZ Racing’s Tarmac Rally damping, tuned to handle the abrupt hits a stage throws up rather than the smoother inputs of a circuit.

What this coilover does for your 2010-2017 BMW X3 F25 4WD

On a 2010-2017 BMW X3 F25 4WD, the biggest change you’ll feel is how the front end absorbs a mid-corner ridge or pothole edge without kicking the nose off line. The damper is built to soak up the jolt from a big hit rather than pass it straight into the chassis, which keeps the tyre’s contact patch working instead of skipping. That directly affects traction out of loose or damp corners, where the X3’s xDrive system can only put power down if the tyre is actually loaded. Stability through fast direction changes improves too – with the body kept flatter over compressions, the car settles sooner after a jump or a crest, so you’re back on the power earlier rather than waiting for the suspension to catch up. Ride height is adjustable as well, letting you set the X3 for stage-specific ground clearance without touching the rest of the set-up.

About the Tarmac Rally coilover

The Tarmac Rally coilover is XYZ Racing’s damper tune built specifically for sealed-stage rallying on tarmac, where the surface is rougher and more uneven than a circuit but still offers a consistent, high-grip base unlike gravel. The valving is set to soak up sharp, large-amplitude hits – broken tarmac, patched sections, kerb strikes – without letting that energy translate into body shock, which is what causes an SUV chassis like the X3’s to pitch and lose composure mid-stage. Keeping the body settled is what preserves tyre traction through the hit rather than letting the wheel unload and skip across the surface. The result is handling that stays predictable as a stage surface degrades, rather than getting progressively harder to read. XYZ Racing carried this damping curve directly from its own tarmac rally programme into the retail kit, rather than adapting a circuit tune for rally use.

Fitment for the BMW X3 F25 (2010-2017)

This kit is built specifically for the BMW X3 F25 4WD, chassis code BM79, covering model years 2010 to 2017. It’s matched to the xDrive four-wheel-drive platform of this generation, so confirm your X3 falls within that production window and drivetrain before ordering.
