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

The F83 M4 convertible carries extra scuttle bracing and a folding hard-top mechanism the coupe never had to deal with, and that extra mass sits low and rearward, right where the factory’s electronically controlled dampers were tuned to compensate for it. Fit a manual coilover to a car built around adaptive damping and the BMW’s electronics will fight you with fault codes and warning lights unless the swap is handled properly.

This XYZ Racing Racing Spec application is built for exactly that: it pairs the coilover with the rear-integrated hardware and cancellation kit needed to remove the electronic damping system cleanly, so the BMW’s EDC control unit stops looking for dampers that are no longer there. Racing Spec is XYZ Racing’s top-tier coilover, aimed at drivers running an M4 on circuit or in serious time-attack events rather than weekend road use.

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

With the OEM electronic damping cancelled and manual control in its place, you get consistent, repeatable damping behaviour instead of a system that’s constantly recalculating itself mid-corner. That matters on the F83 in particular: the convertible’s added weight over the rear axle makes body control under trail-braking and mid-corner load transfer more work for the suspension than it is on the coupe, and a fixed, driver-set damping curve removes one variable from that equation. The modified rear-integrated mounting hardware keeps the multi-link rear geometry correctly located once the factory dampers are out, so camber and toe behaviour under compression stay where BMW’s engineers put them rather than drifting as aftermarket parts flex against OEM brackets. Ride height is adjustable independently of spring preload, letting you set a track-day stance without giving up the compliance you need to get heat into the tyres over a full session.

About the Racing Spec coilover

Racing Spec is the damper XYZ Racing builds specifically for track and racing use, and the base valving comes directly from work done in touring car competition, including WTCC entries, rather than being adapted down from a road-biased product. For cars carrying heavier modifications – bigger brakes, aero, a built engine, or anything else that changes how load moves through the chassis – XYZ Racing will build a bespoke shock absorber to match, using details you supply about the car’s specification and the circuits it runs. That custom-build route exists because a genuinely modified M4 doesn’t behave like a stock one, and a damper calibrated for stock loads won’t suit it.

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

This kit is built for the F83 M4 convertible, chassis code BM95-C, across the full 2014-2020 production run, and includes the rear-integrated modified mounting and the cancellation kit required to disable the factory electronic damping control. Confirm your car uses the standard EDC-equipped rear suspension before ordering.
