Powerflex Black Series Caster-Adjustable Front Lower Control Arm Rear Bushes for Ford Fiesta ST Mk7 2013-on, Polyurethane - PFF19-1502GBLK

Part number: PFF19-1502GBLK

Unlock sharper turn in, stronger self centring and rock solid front end stability on your Ford Fiesta ST Mk7 with these Powerflex Black Series caster-increase front wishbone rear mounts. Built from motorsport grade polyurethane in a 95A durometer, this offset bushing kit replaces the soft OE rubber at the wishbone-to-chassis rear location, tightening geometry control under braking and hard cornering. If you track your ST180 or want a fast road handling upgrade that actually delivers, this is the go to solution.

We run these on our own builds and customer cars and the difference is immediate. Faster steering response, calmer behaviour on bumpy B-roads, more confidence on circuit and repeatable alignment settings session after session. The pre-assembled press-in cartridge with PU ball design makes installation more straightforward than traditional bushes while providing the precision and durability you expect from the Black Series.

Key benefits

• Reduced compliance at the front arm rear pivot for crisper feedback and predictable handling

Who is it for

Fitting and setup

Professional installation and a four wheel alignment are recommended to set caster correctly and maximise tyre life. For expert fitting and geometry setup, book with MJ Modifications, Warwickshire. Request a quote at info@mjmodifications.co.uk.
