Turner Motorsport Spherical Bearing Monoball Rear Shock/Strut Mount (RSM) - BMW 3 Series E30 E36 E46 M3, Z3 & Z4 (E85/E86/E89) - Pillowball Solid Rear Damper Top Mount/Top Hat - Track/Drift/Fast Road

Race-bred spherical rear top mounts for BMW E36, E46, Z3 and Z4

Unlock sharper handling and consistent damping control with this Turner race-spec rear damper top mount. The motorsport-grade spherical bearing replaces the soft rubber element to cut out flex, resist misalignment and allow the shock to articulate freely through its full travel. The result is a tighter rear end, predictable grip and a more connected feel on road and circuit.

We have installed these in-house and on customer builds. Feedback is consistently positive for fast-road, track day and drift use. If you are chasing precision from your suspension, this is a proven upgrade that delivers.

Why enthusiasts choose this upgrade

• Spherical bearing rear strut mount for precise damper control
