Powerflex Road Series Rear Subframe Front Bush Insert for BMW F-Series

Unlock sharper handling, rear-end stability and confidence with the Powerflex Road Series rear subframe front bush insert. This durable polyurethane insert is engineered to fit into and fill the voids of the original BMW rubber bush, helping to reduce subframe movement under acceleration, braking and cornering. The result is a more planted BMW 1 Series, 2 Series, 3 Series and 4 Series that turns in crisply, tracks straight and puts power down more effectively.

At Nforcd we have fitted these inserts to our own cars and for countless customers, and the feedback is consistently positive. Expect a tauter rear axle, improved traction and a more precise feel without sacrificing everyday usability.
