Powerflex Black Series 25 mm Front Sway Bar Chassis Bush Kit for BMW E60 E61 E63 E64 E65 E66 E67 — PFF5-703-25BLK

Unlock sharper turn-in, tighter body control and repeatable handling with these front stabiliser bar D-bushes in the Powerflex Black compound. Designed for demanding use on fast road and track days, this 95 Shore polyurethane insert replaces the soft, ageing rubber that lets the front end wander. Expect crisper steering feel, improved mid-corner stability and long-term durability without the maintenance of solid mounts.
