XYZ Racing Tarmac Rally Coilovers — BMW 1 SERIES F40 3/4 CYL 2019-2026

The F40 is the first 1 Series built on BMW’s transverse UKL platform, and that shift moves weight and drive to the front axle in a way the old rear-driven hatch never had to manage. On a closed tarmac stage, that nose-heavy layout shows up hardest through compressions and over crests, where the front end can unload and skate wide if the damper underneath it can’t keep the tyre loaded.

XYZ Racing’s Tarmac Rally coilover is built around that exact problem. It’s specced for sealed-surface stage work rather than gravel or fast road use, so the priority is keeping the contact patch planted through repeated hard direction changes rather than soaking up long-travel rally jumps.

What this coilover does for your 2019-2026 BMW 1 SERIES F40 3/4 CYL

Fitted to the F40 3/4-cylinder cars, the kit is built to control the sharp weight transfer a front-heavy UKL chassis produces under braking into a stage corner. Instead of the body pitching and loading one corner unevenly, the damper keeps all four contact patches working together, which is what lets you carry more speed through the entry rather than backing off to protect the front tyres. Over broken tarmac and patched stage surfaces, it absorbs the jolt from bigger hits without kicking the car off line, and the reduction in body shock through those moments is what actually recovers lost traction on corner exit. The net effect on a 118i, 120i, 116d or 120d-generation F40 is a car that turns in predictably and stays settled long enough for the driver to commit, stage after stage.

About the Tarmac Rally coilover

The Tarmac Rally is XYZ Racing’s damper for sealed-stage competition, tuned specifically to deal with the way tarmac punishes a car differently to loose surfaces. Its core job is absorbing the impact of an uneven road surface without letting that impact translate into body movement, so a run over a rough patch or a mid-corner ripple doesn’t unsettle the chassis. Where the surface throws up a harder hit, the damper is built to suppress the resulting shock through the body rather than passing it straight to the chassis, which is what protects tyre contact and keeps grip consistent through the rest of the corner. The settings baked into this kit come directly from XYZ’s own Tarmac Rally programme, rather than being adapted from a road-car base tune, and the result is a platform that holds its line and stays composed rather than reacting late to what the surface throws at it.

Fitment for the BMW 1 Series F40 3/4 CYL (2019-2026)

This kit is built for the BMW 1 Series F40, chassis code BM109, covering 3 and 4-cylinder petrol and diesel variants across the 2019-2026 production run. Confirm your exact engine code and drivetrain (front-wheel or xDrive) against your V5 before ordering, as damper and mount specification differs between variants within the F40 range.
