Powerflex Black Series PFF5-6101GBLK uses a super-stiff 95 Shore compound and a fixed 6 mm offset to dial in extra caster for sharper turn-in, better stability under hard braking and more confident fast-road and track-day performance. A direct swap for the factory rubber mount (replaces OE 31126777653), this poly bush kit tightens up the front lower arm assembly for precise geometry control and repeatable handling.\u003c\/p\u003e\n\n  \u003cul\u003e\n    \u003cli\u003e6 mm caster correction adds roughly ±0.5° caster for improved straight-line stability and steering self-centring\u003c\/li\u003e\n    \u003cli\u003eMore negative camber on lock for increased tyre contact patch and front-end bite through corners\u003c\/li\u003e\n    \u003cli\u003e95 Shore polyurethane minimises deflection for consistent alignment under load\u003c\/li\u003e\n    \u003cli\u003eMotorsport-focused feel for circuit, sprint and fast road without the short life of soft rubber\u003c\/li\u003e\n    \u003cli\u003eDirect replacement for the BMW thrust arm bush to cure vague steering and reduce shimmy\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003cp\u003eWe run these bushes on our own builds and customer cars, and the feedback is exactly what keen drivers want to hear: crisper initial response, calmer braking, and a planted front axle on bumpy B-roads and during hard laps.
