What this insert does

This insert pairs with the factory rubber mount to stiffen the rear sub-frame connection, tightening the rear end without the harshness associated with solid mounts. Expect crisper responses, better traction out of bends and a more planted feel under braking and acceleration. Our workshop has fitted many sets with excellent feedback on road manners and performance gains.

Looking for a complete replacement bush
