In front-heavy, front-engine, front-wheel-drive cars, controlling vehicle body roll is key to managing understeer. A larger anti-roll bar is normally used to minimise weight transfer, thus reducing body-roll but heavy use and age can wear the rubber bushes used to mount the bar to the chassis, reducing effectiveness. PFF25-903-23 Front Anti Roll Bar Bush is made in our stiffest Black 95ShA material, complete with knurled bore for better grease retention and designed to re-use existing hardware, whilst providing an increase in rigidity, performance and longevity over the OE rubber bush.
