PFF5-703-28BLK Front Bar Bush Kit 28 mm for BMW E60 E61 E63 E64 E65 E66 E67

Give your BMW a sharper, more connected front end with this Powerflex Black Series 28 mm front bar bush kit. Built from competition-grade polyurethane, these inserts clamp the bar securely to the chassis so the bar can do its job, delivering flatter cornering, cleaner steering input and repeatable handling on fast road and circuit driving. We run these on customer builds and feedback has been outstanding for feel, control and durability.

Why enthusiasts choose this upgrade
