Powerflex PFF5-4001 Black Series Front Radius Arm to Chassis Bush (Pair) for BMW E82 1M, E90/E92/E93 M3, F80 M3, F82/F83 M4, F87 M2 Polyurethane Control Arm/Tension Strut/Thrust Arm Bush

Sharper turn in, stronger braking confidence and rock steady alignment for your BMW M

Transform front end response on your E82 1M, E90 E92 E93 M3, F80 M3, F82 F83 M4 or F87 M2 with this motorsport-grade poly bush pair, part number PFF5-4001. Built in Powerflex Black Series material, these front arm rear mount bushes replace the factory rubber units to cut deflection, lock in caster and give consistent geometry under load. Expect crisper steering, better stability on the brakes and cleaner tyre wear on fast road and track day cars.

Also known as front caster bushes, lollipop bushes, lower wishbone rear mounts, front arm rear bushings and tension strut rear mounts, this set is a direct-fit upgrade for the front lower arm rear location on the listed BMW M models.

Why enthusiasts choose PFF5-4001

• 18 percent stiffer than factory rubber for precise steering feel and feedback
• Reduces fore and aft movement to improve braking stability and turn-in
• Keeps alignment true during hard cornering for predictable handling
• Durable polyurethane resists oil, salt and road grime for long service life
• Ideal for spirited road use and circuit sessions
• Direct replacement pair for the front lower arm rear position

We run these bushes on our own builds and customers consistently report tighter front end control, more confidence on turn in and a more connected feel without harshness.
