Powerflex PFF5-5601GM3 Caster Offset Front Wishbone Rear Bushes for BMW E46 M3 2001-2006 - Eccentric Lollipop/FCAB Polybush Control Arm Mounts (Pair)

Powerflex PFF5-5601GM3 Caster-Increase Bush Set for BMW E46 M3

Transform the front-end feel of your E46 M3 with the Powerflex PFF5-5601GM3 offset rear mounts for the front lower arm. This precision-engineered, rotating polyurethane insert with a hard-anodised aluminium outer dramatically reduces unwanted arm movement, tightens up geometry under load and delivers crisper steering, straighter tracking and greater braking stability on fast road and performance builds.

Compared with the non-offset PFF5-5601M3, this version provides approximately +0.5 increase in caster for improved straight-line stability and sharper turn-in. It is the higher-performance alternative to PFF5-4601M3. We run these on our own projects and have installed them for many customers with consistently excellent feedback on front-end response and road holding.

Why this upgrade works

• Offset design increases caster for enhanced stability and more confident turn-in
• Hard-anodised aluminium shell with a low-friction, rotating polyurethane centre to cut bind and reduce load on the arm
• Significantly reduces lower arm deflection for tighter, more consistent geometry
• Noticeably cleaner steering feedback and better tracking under acceleration and braking
• Backed by the Powerflex Lifetime Warranty

Measured improvements

• Approx. 128 percent stiffness increase over the original rubber mount
• Black Series variant is a further 28 percent stiffer for a total of 190 percent over OE
