My shop installed these on my 08 Wing along with a new set of Elite 3 tires. That was 4500 miles ago. Today there is cupping on one side of the front tire. Also the front tire bounces and feels very unstable at speeds over 80 mph. The only thing I can attribute this to is the Centramatic balancers. My mechanic agrees and next week they are being removed and replaced with dyna beads. I'm writing this review to help others avoid the costly mistake I made a few years ago.
