BMW E46 E46 M3 E85 E86 Z4 Z4 M Solid Aluminium Rear Subframe Bushings Kit

Millway Motorsport solid aluminium rear subframe bushings for the E46, E46 M3, E85, E86, Z4 and Z4 M. A true bolt-on upgrade - no modifications, no machining, no guesswork.

Replaces spongy rubber with rigid aluminium to eliminate subframe movement, sharpen turn-in and lock in rear geometry under load. Ideal for fast-road use or track day prep where precision matters more than plushness.

• Complete set - all positions covered
• Direct fit: reuses original bolts and brackets
• Firmer ride is expected - this is a performance part, not a comfort mod
• Proven on E46 M3 and Z4 M chassis where wheel hop and traction loss are common
