XYZ Racing Tarmac Rally Coilovers — BMW 4 SERIES F83 M4 (Modified Rear Integrated) (Cancellation Kit for Electronic Damping) 2014-2020

The F83 M4’s factory Adaptive M suspension runs everything through electronically controlled dampers, which is exactly what makes fitting a static coilover kit awkward without the right supporting hardware. This is the cancellation kit for electronic damping variant of the Tarmac Rally coilover – a full coilover kit for the BMW 4 Series F83 M4 paired with the resistor kit that satisfies the car’s EDC wiring, so the S55 twin-turbo six can be pointed down a stage without a suspension fault lit up on the iDrive screen.

Tarmac Rally is XYZ’s stage-spec build, tuned around the repeated hard compressions and mid-corner loading of flowing tarmac routes rather than the long-travel articulation gravel rallying needs. On a convertible chassis carrying extra weight low in the rear from the folding roof mechanism, that distinction matters – the rear axle sees more load transfer under braking and direction changes than the coupe, and this kit’s settings are built around managing that.

What this coilover does for your 2014-2020 BMW 4 Series F83 M4

Fitted to the F83, this kit is built to soak up the impact of broken and uneven tarmac rather than transmitting it straight into the chassis – the kind of surface a closed stage throws up more often than a smooth circuit. Across sharp compressions and big bumps the damper is tuned to absorb the jolt rather than let it kick the body, which keeps the tyre loaded and gripping instead of skipping. That control over body movement is what settles the car through a stage: less pitch under braking, less roll transferring weight off the inside rear tyre, and a platform that stays predictable when the road surface doesn’t. For a convertible carrying its own weight distribution quirks, that stability is felt directly in how confidently you can lean on the rear axle exiting a corner.

About the Tarmac Rally coilover

The Tarmac Rally coilover is XYZ’s purpose-tuned kit for sealed-stage tarmac rally driving, built to take the repeated big-hit loading that closed-road stages generate without the damper losing composure. Internal valving is set to absorb impact from uneven pavement and larger bumps while suppressing excess body movement, so the contact patch stays planted and tyre traction holds up where a softer road-biased setup would let the car skip. The result is a chassis that holds its line through the kind of surface changes a stage throws at it, rather than one tuned purely around a smooth track surface. XYZ has carried its settings for this kit directly from its own Tarmac Rally racing programme, so the damping characteristics reflect what the team has run competitively rather than a generic road tune adapted after the fact. For the F83 M4 specifically, this application is built with the cancellation kit for electronic damping included, addressing the car’s factory EDC wiring as part of the fitment rather than leaving it as an afterthought.

Fitment for the BMW 4 Series F83 M4 (2014-2020)

This kit is built for the F83-chassis BMW 4 Series M4, covering the 2014-2020 production run, in the modified rear-integrated configuration with the electronic damping cancellation kit included for cars specified with factory Adaptive M suspension. Confirm your car carries the factory electronic damping option before ordering, as this is the cancellation-kit application rather than the standard static kit.
