Turner Motorsport Aluminum Solid Subframe Mount Kit F22/F23/F30/F32/F33/F36

Transform the way your BMW drives with a precision‑machined aluminium rear sub‑frame mount upgrade for F22, F23, F30, F32, F33 and F36 models. This rigid rear axle carrier mount kit replaces the soft factory bushes to lock the chassis and drivetrain together, delivering laser‑sharp geometry control, repeatable alignment under load and a planted, confidence‑inspiring rear end on fast road, track days and spirited B‑road driving.

Factory rubber bushes compress and deflect, letting the cradle shift when you corner, accelerate and brake. Swap to solid aluminium mounts to eliminate sub‑frame movement and banish the soggy, unpredictable feel. Expect crisper turn‑in, improved traction out of bends, reduced wheel hop and far better stability at speed. We run these mounts on our own builds and our customers consistently report a night‑and‑day improvement in chassis precision while remaining totally usable for daily driving. There is a modest increase in NVH, but the pay‑off in feedback and control is absolutely worth it.
