Powerflex Poly Front Lower Control Arm/Wishbone Rear Bush & Carrier/Bracket Kit (LCAB/FCAB, 66mm Lollipop) for BMW E46 3 Series incl Compact & Z4 E85/E86 Non-M - PFF5K-4601

Sharpen your BMW’s steering with uprated polyurethane control arm rear mounts. This complete carrier and bush set transforms front-end response by reducing unwanted movement at the rear position of the lower arm. Expect crisper turn-in, better stability under braking and more consistent alignment on fast-road and track use while remaining perfectly usable for daily driving.

Built around Powerflex polyurethane inserts and brand-new CTE housings, this kit arrives pre-assembled for a simple bolt-on swap. No press. No hassle. Just remove your old “lollipop” carriers and install these for an immediate suspension refresh.
