XYZ Racing Circuit Master Coilovers — BMW 3 SERIES F34 4/6 CYL (excl. M-Technik. xDrive & EDC) (Modified Rear Integrated) 2013-2026

The F34 Gran Turismo carries more weight over its axles than the F30 saloon it’s built from – a longer wheelbase and a heavier five-door body that BMW never really set up for circuit driving. XYZ Racing’s Circuit Master coilover exists for owners who want to correct that, giving the F34 4/6-cylinder chassis (excluding M-Technik, xDrive and EDC-equipped cars) the wheel control needed for sustained lap sessions rather than the occasional B-road blast.

This sits at the top of the XYZ Racing coilover range, built around independently adjustable damping circuits rather than a single compromise setting. On a 3 Series GT running back-to-back sessions, that separation matters more than outright spring rate – it’s what keeps the platform consistent as tyre temperatures and track surface change across a session.

What this coilover does for your 2013-2026 BMW 3 Series F34 4/6 CYL (excl. M-Technik, xDrive & EDC) (Modified Rr Integrated)

Fitted to the F34, the Circuit Master coilover firms up body control through the direction changes this longer-wheelbase GT resists by default, cutting the roll that builds through fast transitions on a circuit lap. The separate adjustment knobs let you set compression and rebound independently, so you can sharpen turn-in at the front without making the rear ride harsh over kerbs – a real consideration on a car this size and weight. Ride height adjusts at each corner, useful for correcting the nose-heavy stance the 4-cylinder F34 carries and for levelling the car once you’ve settled on a spring rate. The wide damping range means you can back the setup off for the drive home and firm it back up before the next session, rather than settling for one fixed compromise.

About the Circuit Master coilover

Circuit Master is the version of the XYZ Racing range built specifically around sustained lap-time work rather than drift or rally use – the same 3-knob, high-resolution architecture also underpins XYZ’s Racing Spec, Drift Spec and Tarmac Rally lines, but this tune is aimed squarely at circuit driving. The damper offers 9,720 individual adjustment combinations across its 3 external knobs, enough resolution to set low-speed compression, high-speed compression and rebound separately instead of compromising them into one dial. XYZ runs this damper across its racing teams internationally, and the tuning reflects that brief: consistency held across a full session rather than outright plushness. One thing worth knowing before you fit it – the small oil passage built into each knob can produce a faint noise over sharp bumps or kerbing. That’s the design doing its job, not a fault, and it has no effect on damping performance on a circuit.

Fitment for the BMW 3 Series F34 4/6 CYL (excl. M-Technik, xDrive & EDC) (Modified Rr Integrated) (2013-2026)

This kit is built for the F34-chassis 3 Series (BM101), covering 4 and 6-cylinder cars from 2013 to 2026, excluding M-Technik, xDrive and EDC-equipped variants, with a modified rear-integrated mounting specific to this chassis. Confirm your car doesn’t fall into one of those excluded specs before ordering – the rear geometry and electronic damping integration on those variants differ enough to need a separate kit.
