Real-world feedback

We run these on our own cars and our customers consistently report a tighter front end, improved straight-line stability and a noticeable reduction in brake shudder and B-road wobble. If your E61 feels vague on turn-in, tramlined or shows inner-shoulder tyre wear, refreshing the reaction rod bushings with PFF5-701 is a proven solution.
