XYZ Racing Circuit Master Coilovers — BMW 7 SERIES G11/G12 2015-2022

The G11/G12 7 Series is a 2-tonne luxury saloon with air-sprung pretensions, and turning one into a credible circuit car is a specific problem: long wheelbase, soft factory damping calibrated for executive isolation, and a heavy nose that doesn’t want to change direction under load. The Circuit Master is the spec in the XYZ Racing range built for that problem – sustained lap-time work, not a fast-road compromise.

For owners running a G11 or G12 in trackday trim – whether that’s a 730d converted to a high-speed cruiser-turned-track-tool, or a 750i / M760Li being driven well outside its design brief – this is the coilover engineered to keep the chassis composed when a softer kit would have given up two laps in.

What this coilover does for your 2015-2022 Bmw 7 Series G11/G12

Replacing the factory air suspension with a properly valved coilover transforms how the G11/G12 loads its front axle. Body roll drops, mid-corner attitude becomes something you steer with rather than wait out, and the long wheelbase finally translates into stability instead of inertia. The Circuit Master’s 9720 adjustment combinations – three separate knobs governing high-speed bump, low-speed bump, and rebound – let you build a damper map that holds the nose flat through fast direction changes and keeps the rear planted under power. Pitch under braking is brought under control, which matters on a car this heavy when you’re hauling it down from three-figure speeds into a hairpin. Ride height drops to a sensible competition stance without binding the suspension geometry on a chassis that was never designed to sit on coils.

About the Circuit Master coilover

The Circuit Master is XYZ Racing’s circuit-development spec, shared in design language with their Racing Spec, Drift Spec and Tarmac Rally dampers. The headline is the three-knob adjustment system: 9720 combinations across high-speed compression, low-speed compression and rebound, allowing the damper curve to be shaped to a specific track surface and driving style rather than collapsed onto a single click count. Development was done with XYZ racing teams on international circuits, with long-cycle endurance testing in mind. One characteristic of the design – and XYZ are open about this – is that the three-knob valving uses small oil passages, so over sharp road bumps you may hear a faint hydraulic note as oil moves through the smaller adjustment circuit. On a track surface, where the kit is intended to live, there are no bumps sharp enough to provoke it. This is a circuit damper first; the noise on the road is the trade-off for the resolution on the track.

Fitment for the Bmw 7 Series G11/G12 (2015-2022)

This kit is built specifically for the G11 short-wheelbase and G12 long-wheelbase 7 Series chassis, covering the 2015 to 2022 production run under the BM124 application code. The kit replaces the factory air suspension hardware front and rear; confirm your car’s existing suspension configuration before ordering as the G11/G12 range was offered with both air and conventional setups across trim variants.
