E46 E36 Z4 Dinan Rear Trailing Arm Monoball RTAB Kit 18-1102

Dinan’s 18-1102 RTAB kit replaces the rubber trailing arm bushings on E36, E46 and Z4 (E85/E86) with sealed monoballs - no squeaks, no deflection, no compromise on daily drivability.

• Direct fit for E36 318i/323i/328i/M3, E46 318i/320i/323i/325i/328i/330i/M3, Z4 2.5i/3.0i/M
• Stage 1 or fast road upgrade: sharper turn-in, zero rear axle wander under power, no brake shimmy
• Track day proven: handles repeated heat and load without binding or wear - unlike budget sphericals
• Sealed aluminium housings + rubber boots = long life, zero NVH penalty, no greasing needed
• Not for show cars or OEM-plus builds - this is a functional upgrade for drivers who want feedback, not silence
