Turner Motorsport Greasable Control Arm Monoball Upgrade - E46 M3

Unlock laser-precise front-end feel for your BMW E46 M3. This front wishbone pillow-ball bearing kit replaces the factory rubber bush in the front lower arm rear position, delivering razor-sharp steering response, rock-solid braking stability and repeatable alignment on road and track. It is fully serviceable with a built-in grease nipple for easy maintenance and long life.

If your E46 M3 shows vague turn-in, wobble under hard braking or tramlining, tired OEM bushes are usually to blame. Swap to this spherical bearing conversion and remove unwanted compliance without adding harshness. The sealed bearing’s low-friction articulation keeps the front axle planted and predictable, giving you confidence on B-roads, track days and everything in between.

We run this setup on our own builds and customers’ cars. Feedback is consistently the same: tighter, cleaner steering, improved braking feedback and a calmer front end over bumps, with minimal change in cabin noise or vibration.
