Why we rate it

We run these bushes on our own builds and for customer cars. Feedback is consistently excellent for fast-road driving, with noticeably tighter steering and improved confidence under hard braking while keeping cabin refinement intact.

Need increased caster

If you want a geometry tweak for extra stability and turn-in, choose the caster-offset version: PFF5-1901G.
