Powerflex Poly Bushes Pack — Front Wishbone Rear Bush, Caster Offset — PFF5-5601G — BMW E46 3 Series Compact
Unlock sharper steering feel, greater stability and improved braking confidence with the Powerflex PFF5-5601G front wishbone rear bushes. This caster offset polyurethane bush set is a proven performance upgrade for the BMW E46 3 Series Compact, engineered to tighten up the front suspension geometry for fast-road and track-day driving while remaining perfectly usable on the road.
PFF5-5601G adds an extra +0.5 of caster over PFF5-5601 and is a high performance option to PFF5-4601, delivering crisper turn-in, better self-centring and superior straight-line stability. The hard anodised aluminium outer shell and unique low-friction polyurethane centre bush create a low-resistance, rotating interface that cuts unwanted compliance and reduces forces acting on the arm. The result is less deflection under cornering and braking, more precise steering control and a noticeably tighter front end.
