Why choose Powerflex Black Series?
Powerflex Black Series bushes use a 95 Shore A motorsport-grade polyurethane compound designed to maximise control of chassis geometry under braking, cornering and hard acceleration. Compared with tired factory rubber bushes, these track-focused bushes reduce flex and deformation, delivering more precise alignment control, improved turn-in, better feedback through the steering wheel and more consistent tyre contact on track.
