Transform the way your BMW E63 E64 drives with these uprated rear stabiliser bar bushings from Powerflex. If your original rubber mounts are soft or tired, this 13.5 mm polyurethane upgrade tightens the rear end, boosts steering precision and keeps the car flatter through bends for confidence on B-roads and stability at motorway speeds. Ideal for daily use, spirited driving and fast road setups.

Fitted and tested by our team at MJ Modifications, the improvement is immediate. Crisper turn in, reduced roll and a planted, predictable rear axle, all without harshness. Our customers love the sharper feedback and consistent handling these poly mounts deliver.
