XYZ Racing Circuit Master Coilovers — BMW 4 SERIES F82 M4 (Modified Rear Integrated) 2014-2020

The F82 M4’s rear axle carries more torque than any 3 Series-based M car before it, and the S55’s twin-turbo six adds weight ahead of an axle that already unloads fast under trail-braking. XYZ Racing’s Circuit Master coilover is the range built for that exact scenario: back-to-back laps rather than one hard exit off a B-road.

This sits at the circuit-focused end of XYZ Racing’s coilover range for the F82, set apart from a fast-road kit by both spring rate and how far the damping can be pushed at either extreme. It’s built to hold its settings and ride height across a full track session rather than fading by the final stint.

What this coilover does for your 2014-2020 BMW 4 Series F82 M4

Three external adjustment knobs and 9720 possible combinations mean you can separate low-speed compression from rebound instead of accepting one compromise setting for every circuit you visit. That range matters more on the F82 than on most cars in this class: add rebound control at the rear and you check the snap that catches drivers out when the S55’s torque unloads the inside rear tyre mid-corner. Firm up the front and you cut the nose-dive that shifts weight off the rear axle under braking into the apex, keeping the steering loaded and the car pointed where you left it. Ride height adjustment lets you correct the F82’s factory stance and centre of gravity for circuit use without reaching for spacers or altering geometry elsewhere in the chassis. The net result on a BMW 4 Series F82 M4 built for lapping is a car that turns in, loads and unloads more predictably than it does on the standard adaptive dampers.

About the Circuit Master coilover

Circuit Master sits alongside XYZ Racing’s Racing Spec, Drift Spec and Tarmac Rally ranges as the company’s dedicated competition-focused coilover, developed and proven through XYZ’s own racing teams competing internationally rather than adapted from a road product. The headline figure is 9720 possible adjustment combinations, split across three external knobs, giving a far wider window than a typical two-way or basic sport coilover for setting compression and rebound independently front and rear. That adjustment runs through a small-orifice knob design: oil is metered through narrow passages for fine control, and it means you may hear some extra noise from the dampers over kerbs and rough surfaces. That’s a normal characteristic of this kind of fine-metered valving, not a fault, and it’s the trade XYZ has made in building a coilover for circuit tracks rather than for daily road use. Every BMW 4 Series F82 M4 kit shares that same construction and adjustment range, so the parts you’re fitting are the same spec XYZ’s race teams use.

Fitment for the BMW 4 Series F82 M4 (2014-2020)

This Circuit Master kit is built for the BMW 4 Series F82 M4, chassis code BM93, across the 2014 to 2020 production run, in the modified rear-integrated shock mount configuration. Confirm your car matches that rear mounting spec before ordering, as XYZ lists a separate kit for the standard mount.
