XYZ Racing Circuit Master Coilovers — BMW 4 SERIES F32 4/6 CYL (excl. M-Technik. xDrive & EDC) (Modified Rear Integrated) 2013-2026

Without BMW’s factory EDC electronic dampers in the loop, the rear-wheel-drive F32 4 Series (excluding M-Technik and xDrive cars) gives the Circuit Master coilover a clean passive baseline to work from, rather than a setup fighting a software-controlled damper module. This is chassis code BM100, built 2013 to 2026, and the kit is built for sustained circuit lap-time work rather than a single fast lap or a fast-road compromise.

XYZ Racing has engineered the rear end of this kit around the F32’s modified rear-integrated mounting points, so the coilover ties into the standard suspension pickups instead of requiring you to re-engineer the geometry yourself. That matters on a coupe that’s heavier through the rear structure than its saloon sibling and needs a damper that can control that mass through repeated heavy braking and direction changes.

What this coilover does for your 2013-2026 BMW 4 Series

Fitting this kit gives you 9720 combinations of damping adjustment across the three external knobs, so you can move from a stiffer low-speed compression setting for trail-braking into a corner to a softer high-speed rebound setting for kerb strikes and track surface changes, all without pulling the dampers apart. On a non-M-Technik F32 without EDC, that’s a genuine step up in resolution over the two-mode factory setup, and it lets you keep the front end settled under load into fast corners where the standard suspension would otherwise let the nose push wide. Ride height is adjustable independently of spring preload, so you can drop the car to reduce roll without changing the spring rate you’ve chosen for the circuit. Because the rear geometry is built to the F32’s modified rear-integrated points, the back axle stays planted and predictable when you’re on the throttle out of slow corners, rather than stepping out unpredictably as the standard dampers fade.

About the Circuit Master coilover

The Circuit Master is XYZ Racing’s dedicated circuit damper, developed and run by XYZ racing teams on international circuits over an extended test programme rather than built as a fast-road unit with a track badge stuck on it. Each damper carries three external adjustment knobs feeding a small-oil-hole valving design, which is what delivers the 9720-way adjustment range, letting you tune compression and rebound independently to suit a given circuit or tyre compound rather than accepting one compromise setting. That small-passage valving is deliberate: it’s what gives the fine adjustment resolution, and on rough sections of track it can produce a faint noise as oil moves through the narrow passage. That’s normal operation, not a fault, and it’s the trade-off XYZ Racing has made in favour of adjustment precision on a damper that’s built specifically for track surfaces rather than UK B-roads. The construction is aimed squarely at drivers doing repeat sessions rather than a single timed lap, where consistency across a run matters as much as outright grip.

Fitment for the BMW 4 Series F32 (2013-2026)

This kit is built for the BMW 4 Series F32, chassis code BM100, covering the 2013 to 2026 production span for 4- and 6-cylinder cars. It’s specified for cars without the M-Technik suspension package, without xDrive four-wheel drive, and without factory EDC adaptive dampers, and uses the modified rear-integrated mounting arrangement rather than the standard rear-link pickups.
