500 miles ago I installed the replacement -B mounts on my GT500 with Steeda Competition springs. The ride is better than stock and noise free. No more clunking and the front end is dead silent, the way it should have been from the factory. I also carefully disassembled the new mounts before installation and added a lot of extra water resistant grease to the bearings. I have no doubts that this mount will last a long time.
