Powerflex Polyurethane Stabiliser Bar Mounting Bushes 14.5 mm for BMW 6 Series E63 E64 2003 to 2010 - Part No. PFR5-4609-14.5

Transform the way your BMW 6 Series steers and grips with Powerflex polyurethane rear stabiliser bar mounting bushes. Swapping out tired factory rubber for performance poly instantly tightens chassis response, delivers flatter cornering, improves mid corner stability and keeps the tyre contact patch working harder. Ideal for daily driving and fast road use, these bushes give sharper feedback without harshness, so you enjoy precise control and confidence on every journey.

We run these on our own cars and our customers consistently report crisper turn in, less roll and more predictable handling in all conditions. If your 6 Series feels vague or wanders under braking, this upgrade is a proven fix that lasts.
