Powerflex Poly Bushes Pack – Front Wishbone Rear Bush, Caster Offset – PFF5-5601GM3 – BMW E46 3 Series M3
Unlock sharper steering, improved braking stability and more precise handling on your BMW E46 M3 with the Powerflex PFF5-5601GM3 front wishbone rear bushes. This caster-offset polyurethane bush kit is engineered to increase precision compared to rubber and many OE-style replacements, giving your E46 M3 the control and confidence it deserves on fast road and performance driving.
PFF5-5601GM3 adds approximately +0.5 caster over PFF5-5601M3 and is the high-performance option to PFF5-4601M3. Each bush uses a hard-anodised aluminium outer shell paired with Powerflex’s unique low-friction polyurethane centre. This creates a low-friction, rotating bush that reduces the forces acting on the arm, cuts unwanted lower arm deflection and minimises compliance. The result is noticeably less movement under cornering and braking, with crisper steering feel, straighter tracking and more consistent geometry.
We have fitted these on our own builds and for customers, and the feedback is consistently positive. Expect tighter front-end response, better road holding and improved tyre contact with the road.
