Fitment notes

These inserts slide into the cavities of the original bush, so there is no need to press out the OE component, making this a quick, cost-effective handling upgrade for the F22 and F23 chassis. Ideal for spirited road use where you want a more connected rear axle without turning the car into a track-only setup.

Proven on our cars and with our customers

We have installed and run PFR5-1927 on 2 Series platforms and feedback has been consistently positive. Owners report a more planted back end and cleaner launches with negligible increase in cabin noise. A simple mod that makes the drivetrain feel tighter and more precise.
