Millway Motorsport BMW E36/E46/Z4 (M & M3) Rear Control Arm/Wishbone Spherical Bearings - Uniball/Monoball Pillow Ball Outer Hub/Knuckle Bushes/Bushings, Upper & Lower, Eccentric Camber/Toe Adjustment/Lockout, Pair

Rear wishbone spherical bearing kit for E36, E46 and Z4 (including M and M3) — offset inserts, upper and lower locations, supplied as a pair

Transform the back end of your 3 Series or Z4 with this motorsport-grade monoball conversion. This kit replaces the factory rubber at the hub carrier end of both the upper link and the lower link, locking down rear geometry for crisp response, stronger traction and repeatable alignment on road and track. The offset design gives precise camber and toe correction, helping you dial in the stance and stability you want without the squirm of soft bushes.

What you’ll feel

• Immediate improvement in rear axle control and stability under acceleration, braking and cornering
• Cleaner turn-in, better mid-corner support and more confident exits thanks to reduced deflection
• Consistent alignment settings that stay true lap after lap and mile after mile

Why this bearing kit

• Direct replacement for the outer joint on both rear links (upper and lower) at the wheel carrier
• Offset/eccentric inserts for precise geometry tuning of camber and toe
• Aluminium housings with stainless spacers and precision spherical bearings for durability
• Motorsport-ready construction for fast road, track day, time attack and drift builds
• Sold as a pair

Vehicle fitment

• 3 Series E36, including M3
• 3 Series E46, including M3

Materials

• Aluminium housings

• Spherical (monoball) bearings

We run these on our own builds and have installed them on many customer cars. Feedback is consistently positive: a tighter rear end, more predictable behaviour when pushing on and a direct connection to the road that standard rubber simply cannot match.
