Powerflex PFF5-5601G-60 Front Wishbone/Control Arm Rear Bush, Caster Offset 60mm, BMW E46 3 Series inc Touring - Polyurethane Rotating Bush (Pair)

Powerflex PFF5-5601G-60 Caster-Increase Rear Mount for Front Lower Arm - BMW E46 3-Series inc Touring

Transform the front-end of your E46 with the Powerflex PFF5-5601G-60 rear mount for the front lower arm. Built for cars using the 60 mm lollipop housing, this rotating polybush delivers a noticeable caster increase of approximately +0.5 degree over PFF5-5601-60 for sharper turn-in, rock-solid straight-line stability and confident braking on fast road and track.

Engineered around a hard-anodised aluminium outer shell with a low-friction polyurethane pivot, it is a true rotating design that minimises binding and reduces unwanted forces on the arm. By cutting compliant material inside the housing, the bush dramatically lowers arm deflection, keeping your alignment consistent under load. The result is tighter geometry control, clearer steering feedback and a more planted front axle.
