Powerflex Front Anti Roll Bar Mounting Bush 26.5 mm for BMW Z4 E89 2009 onwards — PFF5-4602-26.5
Transform the steering precision and road holding of your BMW Z4 E89 with this genuine Powerflex polyurethane bush kit. Designed specifically for the front anti-roll bar mounting on the Z4 E89, this 26.5 mm poly bush pack replaces soft, ageing rubber bushes to deliver sharper turn-in, reduced body roll and consistent handling. If you want a faster, more connected drive with improved tyre contact and stability, this Powerflex anti-roll bar bush is the essential upgrade.
Imprecise handling, uneven tyre wear and braking instability are classic symptoms of worn rubber suspension bushes. Powerflex poly bushes control unwanted suspension movement so the anti-roll bar can do its job properly, keeping your tyres in contact with the tarmac and your Z4 feeling planted and predictable in all conditions. Correctly formulated polyurethane also matches or exceeds rubber for noise, vibration and harshness suppression, so you gain control without the compromise.
- Sharper steering response and improved chassis stability
- More consistent geometry under load for predictable handling
- Better tyre contact, helping reduce uneven tyre wear
- Durable polyurethane construction with a lifetime warranty
- Cost-effective performance upgrade for road and fast-road use
