XYZ Racing Circuit Master Coilovers — BMW 5 SERIES G61 i5 (OE FOR REAR AIR STROT) 2024-2026

The G61 i5 is a near-2.3-tonne electric estate riding on factory air at the rear, and that is precisely the platform the Circuit Master is built to wrestle into shape on a circuit. Replacing the OE rear air strut with a coilover changes the car’s character completely – body control becomes immediate, the rear axle stops settling mid-corner, and the chassis finally responds to steering input the way the front end has always wanted it to.

For owners taking a G61 i5 to track days and sprint events, this is the kit that turns a comfortable executive estate into something that can hold a line through a fast sweeper without the rear platform sagging under regen and weight transfer. The Circuit Master sits at the top of the XYZ range for a reason – it is built for sustained lap-time work, not posing.

What this coilover does for your 2024-2026 Bmw 5 Series G61 I5 (OE FOR REAR AIR Strot)

Removing the rear air system and running coilovers front and rear gives the G61 i5 a single, consistent damping curve at every corner – no more lag while the air system decides what to do mid-bend. With 9720 individual adjustment combinations on tap, you can set the car soft enough for a road transit to the circuit and then crank the compression and rebound for the track session itself. The three-knob layout – high-speed compression, low-speed compression, rebound – lets you separate big-hit body control from small-input ride quality, which matters on a car this heavy. Expect sharper turn-in, less mid-corner squat under power, and a far more honest brake platform under late, hard braking from triple-figure speeds.

About the Circuit Master coilover

The Circuit Master is XYZ Racing’s top-tier circuit damper, sitting alongside their Racing Spec, Drift Spec and Tarmac Rally builds. It has been developed and validated by XYZ race teams on international circuits, with long-duration testing that targets the failure modes a track-only damper has to survive – heat soak, repeated big-hit absorption, and consistent performance from cold lap to qualifying lap. The three adjustment knobs feed a small-orifice oil-passage design, which is what allows the 9720-way range; that same small-passage architecture means you may notice a faint hydraulic noise over very large bumps, because the oil is being metered through a tighter circuit than a road damper would use. On a circuit surface that is normal and expected. Construction is geared to one job: track work.
