XYZ Racing Circuit Master Coilovers — BMW 3 SERIES G20 (2WD/4WD) 4/6 CYL (Cancellation Kit for Electronic Damping) 2018-2026

The G20 arrived as BMW’s stiffest-ever 3 Series shell, and on cars specced with adaptive electronic dampers that stiffness works against the factory kit the moment you push past a fast road pace: the standard EDC struts hunt between comfort and sport maps instead of holding one predictable rate through a full circuit lap. This cancellation-kit version of the XYZ Racing Circuit Master coilover removes the electronic damping control from the equation entirely, so 2WD and 4WD G20s, four- and six-cylinder alike, can run a mechanically adjusted circuit setup without the ECU second-guessing the dampers mid-corner.

Circuit Master is XYZ Racing’s dedicated lap-time platform, not a fast-road compromise. On a G20 that carries more weight than any previous 3 Series, that means a kit built to hold its rate through repeated heavy braking into the apex and full-throttle exits, session after session, on a track surface rather than a B-road.

What this coilover does for your 2018-2026 Bmw 3 Series G20 (2WD/4WD) 4/6 CYL (Cancellation Kit for Electronic Damping)

With the electronic damping control taken out of the loop, every adjustment you make at the knob is the one the car actually runs, with no software layer smoothing it out mid-corner. The 9720 available combinations across three separate adjustment knobs let you set compression and rebound independently front and rear, which matters on a chassis carrying meaningfully more mass over the nose than the E9x or F30 it replaces. Ride height drops through the threaded body, correcting the G20’s factory rake and pulling the centre of gravity down before you’ve touched a spring rate. On the xDrive cars, that adjustment range is what lets you balance corner-entry rotation against the extra weight and driveline hardware sitting further back than on the 2WD cars. On track, the net effect is a 3 Series that turns in on your inputs rather than an EDC module’s best guess at what you wanted.

About the Circuit Master coilover

Circuit Master sits at the top of XYZ Racing’s range as the type built specifically for sustained lap-time work rather than road use. XYZ’s own racing teams have run the platform across circuits worldwide, and the 9720-way adjustment count comes directly from that mileage: three separate knobs, each covering its own range, so compression and rebound can be tuned independently rather than moving together on one dial. The monotube-style body uses a small-orifice valving arrangement, a deliberate choice for consistency under sustained load rather than an oversight, so expect a faint noise through sharp kerbs or track expansion joints as oil passes through the small passage – that’s the valving doing its job, not a fault. For this G20 application, the kit is built to run without the factory electronic damping module, so the mechanical settings you choose are the only variable in play. It’s aimed at drivers doing repeat sessions, where a setup has to hold up on the tenth lap the way it did on the first.

Fitment for the Bmw 3 Series G20 (2WD/4WD) 4/6 CYL (Cancellation Kit for Electronic Damping) (2018-2026)

This kit is listed for the G20-generation 3 Series built from 2018 to 2026, chassis code BM106-C, covering both 2WD and xDrive 4WD cars across the four- and six-cylinder engine range. It’s the cancellation-kit specification, matched to G20s originally fitted with electronic adaptive damping rather than passive factory struts. Confirm your car’s chassis code and drivetrain against BM106-C before ordering.
