Powerflex Front Stabiliser Bar Bush Set 27 mm for BMW Z4 M E85 E86 2006 to 2009 - PFF5-4602-27

Transform the front-end feel of your BMW Z4 M with this uprated stabiliser bar bush set from Powerflex. Precision-moulded performance bushes dramatically improve steering feel, reduce body roll delay, and keep geometry consistent under load for confident turn-in and planted grip on B-roads, fast road driving, and track days. We run these on our own Z4 M builds and customer feedback has been outstanding.

Rubber mounts compress and degrade over time. Powerflex polyurethane controls bar movement far more effectively, helping your tyres maintain contact with the tarmac and delivering cleaner feedback through the wheel. Expect tighter chassis control, more even tyre wear, and improved braking stability without a harsh ride.

Key reasons to upgrade

• Crisper steering response and reduced delay before the bar works
• Improved front-end grip and stability in corners and under braking
• Minimised deflection versus ageing rubber for consistent alignment

• Great value handling upgrade that lasts
• Backed by the Powerflex Lifetime Warranty
