PFF5-5601G-60 Caster-Offset Rear Mounts for Front Control Arms - BMW E46 3 Series Compact 60 mm Carrier - Also suits BMW Z4 with 60 mm Bracket

Give your E46 Compact a front end refresh with this pair of caster-offset rear mounts for the front lower arms. Powerflex part number PFF5-5601G-60 uses a hard anodised aluminium outer and a low-resistance rotating polyurethane centre to add approximately +0.5 degree of caster for crisper turn-in, improved straight line confidence and more stable braking on fast road and track day setups.

We have installed these on our own cars and countless customer builds, and the feedback is consistently positive. Expect tighter steering, less tramlining and a more connected feel without the slop of tired factory rubber.
