XYZ Racing Circuit Master Coilovers — BMW 3 SERIES F80 M3 (Modified Rear Integrated) 2014-2018

The F80 M3’s S55 twin-turbo straight six puts 431bhp through the rear axle alone, and the factory adaptive dampers were tuned around a broad comfort-to-stiffness compromise that starts to show its limits once you’re stringing laps together. Add in the double-jointed front axle and a chassis that snaps into rotation once the rear steps out, and the standard set-up runs out of composure exactly where a driver wants more of it: mid-corner direction changes, trail-braking into apexes, and hard throttle application out of slow corners.

The XYZ Racing Circuit Master coilover for the Bmw 3 Series F80 M3 (2014-2018) replaces that factory compromise with a kit built specifically for sustained circuit lap-time work. It’s the range XYZ point at drivers who are on track often enough that damping consistency, not outright comfort, is the priority.

What this coilover does for your 2014-2018 Bmw 3 Series F80 M3 (Modified Rr Integrated)

With 9720 combinations of damping adjustment available through the kit’s external knobs, you can set the F80 up to control its rear-biased weight transfer under braking without over-stiffening the front axle and killing turn-in. That range of adjustment matters on a chassis this heavy at the rear corners: too soft and the S55’s torque overwhelms the rear under power, too hard and the double-jointed front geometry loses the compliance it needs to load progressively. Ride height is also fully adjustable, so you can drop the F80’s centre of gravity for track days and still wind it back up for road use between sessions. The net effect on this chassis is a car that changes direction with less of the mass-carry-through you feel in the standard suspension, and a rear axle you can trust to put power down out of second- and third-gear corners rather than one that steps out on you.

About the Circuit Master coilover

Circuit Master sits at the top of XYZ Racing’s range and is built around the same damper architecture the brand runs with its own racing teams on international circuits. The headline figure is 9720 distinct adjustment combinations, delivered through three external knobs rather than a single compression/rebound dial, which is what lets a driver separate low-speed and high-speed damping instead of compromising on one setting for both. The valving uses a small-oil-hole design through those knobs; on rough sections or big kerbs you may hear a faint noise as oil passes through the passage, which is a normal characteristic of this construction rather than a fault, and it’s tuned around circuit surfaces where that trade-off is worth making. Construction is monotube, which resists heat fade better than a twin-tube design over repeated hot laps, and the kit is built to full ride-height adjustability so the car can be set low for competition and raised again for road driving without swapping parts.

Fitment for the Bmw 3 Series F80 M3 (Modified Rr Integrated) (2014-2018)

This kit is specified for the F80-chassis Bmw M3 built between 2014 and 2018, listed under chassis code BM104 with the modified rear-integrated mounting configuration. Confirm your car falls within that production window before ordering, as F80-generation running gear changed enough year to year that fitment is chassis-code specific rather than generic to "3 Series".
