Powerflex PFF5-4001G Black Series Polyurethane Front Lower Control Arm Rear Bush 5mm Caster Offset (Caster Correction) (Tension/Thrust Arm, Lollipop, Radius Arm to Chassis) for BMW E82 1M, E90 E92 E93 M3, F80 M3, F82 F83 M4, F87 M2

BMW M2 M3 M4 and 1M front lower arm rear bush upgrade PFF5-4001G

Sharpen steering, lock in geometry and cut deflection with this motorsport-grade polyurethane bush kit. Part number PFF5-4001G uses the Black Series compound with a fixed 5 mm offset to add approximately plus or minus 0.5 degree of caster, giving crisper turn in, stronger on-centre feel and improved high speed stability. The uprated material is around 18 percent firmer than the factory rubber, so alignment holds true under braking and hard cornering, boosting confidence on fast road and track day driving.

Also known as the front lower control arm rear bush, tension strut to body bush, thrust arm bush, wishbone rear bush or lollipop bush, this kit is a proven solution for owners who want precise steering feedback and repeatable alignment without the vagueness of ageing OEM parts. We run these bushes on our own builds and customer cars with excellent results for response, grip and consistency.

Key benefits

• Black Series polyurethane for a noticeable increase in rigidity vs stock rubber
• 5 mm caster offset for enhanced steering feel and better straight line stability
• Camber gain on lock for a larger tyre contact patch when cornering
• Reduced bush movement for improved braking stability and geometry control
• Durable, track capable upgrade suited to fast road use
