Real-world benefits

Imprecise handling, uneven tyre wear and braking instability are common symptoms of ageing or soft rubber bushes. Fitting Powerflex polyurethane inserts cures these issues by stabilising the subframe under load. We have installed these for customers and run Powerflex bushes on our own cars, and the feedback is consistently positive on steering precision, stability and overall confidence.
