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

The F83 is BMW’s drop-top take on the S55-engined M4, and that soft-top construction carries real weight and flex the closed F82 doesn’t have to deal with. Every extra kilogram of structure moves through the rear axle under load, which is exactly what the XYZ Racing Top Sport coilover for this chassis (code BM95-C) is built to manage – a kit aimed at occasional track day work without giving up a daily-driveable street car.

Because the F83 left the factory running BMW’s electronically-adjustable M dampers, fitting a fixed coilover here isn’t a straight swap. This listing includes the cancellation kit needed to remove the factory electronic damping control loop cleanly, so there’s no dash warning light left hunting for a sensor that no longer exists, paired with a rear mount reworked to integrate with the standard F83 rear subframe rather than fight it.

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

The S55 twin-turbo straight-six puts down enough torque that a soft, worn rear end will squat and wander under hard throttle – this kit tightens that up with damping set 30-50% firmer than a street base, or roughly 2kg/mm more spring rate depending on the corner, so the extra convertible mass stops overwhelming the standard geometry. Ride height becomes adjustable independent of spring preload, which matters on a car that sits nose-heavy once the twin-turbo block and its cooling hardware are accounted for. On broken UK B-roads the increased damping force takes the edge off sharp-edged bumps and expansion joints rather than letting them jolt straight through the body shell, and the firmer control keeps the rear tyres loaded and gripping through direction changes instead of skipping. For a convertible chassis that already flexes more than the coupe, that additional wheel control does a lot of the stability work the body itself can’t.

About the Top Sport Coilover

XYZ Racing’s Top Sport line sits between full street comfort and dedicated race hardware, built around damping rates roughly a third to a half firmer than the brand’s street settings, or an equivalent 2kg/mm bump in spring rate depending on corner and application. The intent is to absorb the impact of rough tarmac and larger bumps without letting that energy translate into body movement – suppressing shock through the chassis while keeping the contact patch loaded for traction. Ride height and, where the platform allows, damping are adjustable, letting an owner move between a fast-road setting for the commute and a stiffer track setting for a circuit day on the same kit. The valving and spring rates come out of XYZ Racing’s own track programme rather than a generic street catalogue, and the line is pitched specifically at drivers doing track days and aggressive road driving rather than pure show-car stance work.

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

This kit is built for the BMW 4 Series F83 M4, chassis code BM95-C, covering the 2014-2020 production run. It’s specified as the Modified Rr Integrated version with the Cancellation Kit for Electronic Damping included, so it’s intended for F83s that left the factory with BMW’s adaptive M dampers – confirm your car has factory electronic damping control before ordering so the cancellation hardware matches your setup.
