This pair of high-performance polyurethane bushings replaces the factory rubber at the rear mount of the front arm, cutting unwanted movement for crisper turn-in, improved braking stability and consistent geometry on fast road and track. We run these on our own builds and customer cars and the feedback is always the same – sharper, more confidence-inspiring front axle behaviour.\u003c\/p\u003e\n  \n  \u003cp\u003eBuilt from motorsport-grade material that is 18 percent firmer than the original rubber, the PFF5-4001 is engineered to handle the high loads seen at the thrust arm position. The result is reduced deflection under cornering and braking, more accurate caster control and a front end that stays planted when you really lean on it.\u003c\/p\u003e\n  \n  \u003ch3\u003eWhy enthusiasts choose PFF5-4001\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e18 percent stiffer than OE rubber for focused handling and control\u003c\/li\u003e\n    \u003cli\u003eReplaces the rear mount of the front arm for better caster stability and steering feel\u003c\/li\u003e\n    \u003cli\u003eDirect-fit upgrade that resists oil, heat and road contaminants\u003c\/li\u003e\n    \u003cli\u003eProven on fast road, club motorsport and track day cars\u003c\/li\u003e\n    \u003cli\u003eSupplied as a matched pair for one vehicle\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \n  \u003ch3\u003eFitment\u003c\/h3\u003e\n  \u003cp\u003eDesigned for the following BMW M applications:\u003c\/p\u003e\n  \u003cul\u003e\n    \u003cli\u003eBMW E82 1M Coupe\u003c\/li\u003e\n    \u003cli\u003eBMW E90 M3 Saloon, E92 M3 Coupe, E93 M3 Convertible\u003c\/li\u003e\n    \u003cli\u003eBMW F87 M2\u003c\/li\u003e\n    \u003cli\u003eBMW F80 M3\u003c\/li\u003e\n    \u003cli\u003eBMW F82 M4 Coupe, F83 M4 Convertible\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003cp\u003eAlso known as thrust arm bush, caster arm bushing, guide rod rear mount, wishbone rear bush, front arm rear bushing, front control arm rear silentblock.\u003c\/p\u003e\n  \n  \u003ch3\u003eWhat you receive\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2 x polyurethane bush assemblies\u003c\/li\u003e\n    \u003cli\u003eSufficient for one car\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \n  \u003ch3\u003ePart numbers\u003c\/h3\u003e\n  \u003cp\u003e\u003cstrong\u003ePowerflex Part Number:\u003c\/strong\u003e PFF5-4001\u003c\/p\u003e\n  \u003cp\u003e\u003cstrong\u003eOEM cross-references:\u003c\/strong\u003e 31122284531, 31122284532, 31122283579\u003c\/p\u003e\n  \n  \u003ch3\u003eReal-world benefits\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eCleaner turn-in and front-end bite when attacking B-roads or circuits\u003c\/li\u003e\n    \u003cli\u003eMore stable braking with less shimmy through the wheel\u003c\/li\u003e\n    \u003cli\u003eHolds alignment better to help reduce uneven tyre wear\u003c\/li\u003e\n    \u003cli\u003eConsistent handling lap after lap compared with ageing factory rubber\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \n  \u003ch3\u003eFitting and alignment\u003c\/h3\u003e\n  \u003cp\u003eProfessional installation is recommended.
