Millway Motorsport Solid Aluminium Rear Subframe Bushings/Bushes & Mounts Kit for BMW E46 & E46 M3, E85/E86 Z4 & Z4 M Complete Vehicle Set

Millway Motorsport Billet Alloy Rear Cradle Mount Kit for BMW 3 Series E46 and Z4 E85/E86 including M3 and Z4M — Complete Car Set

Transform the way your BMW drives with Millway Motorsport’s billet alloy rear cradle mounts. This complete car set replaces the factory rubber with precision aluminium for a locked-in rear axle, laser-accurate geometry and a more connected, confidence-inspiring feel on fast road and track. If you want a tighter, more stable rear end with direct feedback and repeatable handling, this is the upgrade that delivers.

We have fitted these to our own builds and many customer cars at MJ Modifications. The result is consistently outstanding: sharper turn-in, improved traction, and far better stability under throttle and braking. It is a proper motorsport-grade solution for drivers who demand control and durability.

Why upgrade to rigid rear cradle mounts

• Razor-sharp response from the rear axle for precise cornering and predictable balance.
• Keeps alignment and suspension geometry true under load to reduce toe change and squirm.
• Helps cut axle tramp and wheel hop for cleaner launches and stronger traction out of bends.
• Improves stability through high-speed transitions and heavy braking.
• Ideal for track days, time attack, sprint, drifting and focused fast-road setups.

Key features

• Solid alloy construction for uncompromising rigidity and long-term reliability.
• Direct-fit replacement in the factory locations — no cutting or extra parts required.
• Optimised fitment for BMW E46 3 Series including M3, and BMW Z4 E85/E86 including Z4M.
• Supplied as a complete vehicle set for a full rear cradle refresh.
