Transform the rear end of your BMW Z3 with this adjustable polyurethane trailing arm bush kit. Designed to give precise alignment control, these bushes allow rear camber and toe fine-tuning of ±1° directly at the arm, helping you correct geometry, reduce inside-edge tyre wear and unlock sharper, more confidence-inspiring handling for fast road and track use.

Factory rubber components soften and deflect over time, which leads to vague steering, tramlining and instability under braking. This polyurethane solution resists flex, oil and heat, keeping the rear axle located accurately so the car stays planted, predictable and responsive. Expect crisper turn-in, improved traction on corner exit and more consistent tyre contact with the tarmac.

• ±1° rear camber and toe adjustment for precise alignment and tyre life
• High-performance polyurethane bushings control unwanted movement without a harsh ride
• Direct replacement for tired OEM rubber parts, no permanent modification required
• Optimises grip, stability and braking performance for road, track day and spirited driving
• Helps cure tramlining, rear-end wander and uneven wear on the inner shoulder
• Durable and resistant to oil, fuel and heat for long service life
• Lifetime warranty from the manufacturer for peace of mind

We have installed this kit on customer Z3s and the feedback is consistently excellent. Owners report a more planted rear axle, cleaner turn-in and a noticeable reduction in tyre scrub once correctly set up. It is a straightforward, worthwhile suspension upgrade that makes the car feel tight and composed again.

What is included

• 4 x adjustable rear trailing arm polyurethane bushes
