034Motorsport Billet Aluminium Rear Axle Carrier Insert Set for BMW E8X and E9X

Unlock sharper chassis response and put power down with confidence. This precision engineered 034Motorsport rear cradle insert set clamps the OEM rubber mounts on your BMW 1 Series and 3 Series E8X and E9X platform to curb unwanted cradle movement, preserve alignment under load, and deliver a planted rear end on fast road and track. Expect tighter turn in, cleaner launches, reduced hop and far more predictable handling with near stock-like cabin refinement.

We run these on our own builds and have fitted them for many customers at MJ Modifications in Warwickshire. Feedback is consistently glowing, with drivers reporting crisper steering, improved traction out of bends and a calmer rear axle over bumpy surfaces. If you want a no-compromise handling upgrade without the hassle of pressing out factory bushes, this is the smart solution.
