XYZ Racing Racing Spec Coilovers — BMW 4 SERIES F83 M4 (Cancellation Kit for Electronic Damping) 2014-2020

The F83 M4 Convertible’s open-top structure was already a compromise the chassis engineers spent years masking, and the factory Adaptive M Suspension was the software layer holding that compromise together. Strip the electronics out and you need a mechanical damper that earns its keep without an ECU smoothing over the cracks. The XYZ Racing Racing Spec coilover for the Bmw 4 Series F83 M4 (Cancellation Kit for Electronic Damping) does exactly that – a fully mechanical, race-derived setup with the cancellation kit included so the dashboard stays quiet after install.

This is the hardest specification XYZ Racing builds for the F83 platform. Settings are drawn directly from the brand’s WTCC campaign data, which means the damping curves were sorted on circuits before they were sorted on spec sheets. For a 425bhp S55-powered convertible heading to track days and time-attack rounds, that pedigree matters more than another generic "sport" coilover would.

What this coilover does for your 2014-2020 Bmw 4 Series F83 M4 (cancellation Kit For Electronic Damping)

The Racing Spec damping is sorted for high-load circuit work, so the front end stays planted under hard trail-braking into a fast right-hander rather than diving and unloading the inside rear. The S55’s torque arrives in a hurry, and a stiffer, properly valved damper stops the rear squatting and washing wide on corner exit – a recurring complaint on the soft-roof M4. Cabriolet scuttle shake is the F83’s signature weakness, and the higher spring rates plus tighter damping reduce the shimmy you feel through the steering column over mid-corner bumps. The included cancellation kit suppresses the EDC fault codes that would otherwise light up the dash the moment the OE struts are unplugged. Ride height is fully adjustable so corner-weighting the convertible properly is finally an option, not a workshop wish.

About the Racing Spec coilover

Racing Spec is XYZ Racing’s circuit-focused damper, developed through direct participation in WTCC competition rather than dyno-bench guesswork. Settings – spring rates, valving, bump and rebound progression – were arrived at on actual race weekends, then carried over to the customer-spec part. For owners running aggressive supporting modifications or competing in series with their own tyre and aero rules, XYZ offers custom shock absorber builds: supply the upgrade list and the circuit, and the damper is built to that brief. This is closer to the factory-racing approach than a catalogue-spec coilover, which is why Racing Spec sits at the top of the family. Construction follows XYZ’s full-spec layout for circuit use, and the cancellation harness for the F83’s EDC system is bundled in the box rather than sold as a chargeable extra.
