We have been using the Super Pro bushings for years in all of our street and race Minis/ They are also what we install in customer vehicles at the shop. These are the best bushings by far. They are harder than any other cheaper poly bushings which increases steering feel but they don't transmit more road noise than the stock bushings. We carry Control arm bushings, engine support bushings, supercharger belt tensioner, front sway bar, rear sway bar, gearbox, lateral arm, and steering rack bushings.
