What year Treg were these for? Did you have to follow the VW TSB mounting them on the vehicle? No steering wheel shake is great. Maybe RFB is for tires that are more problematic. Gives me hope with the Toyo's. Can't wait for mine to get here (this Thursday).Had the Toyo's installed yesterday at the local NTB. They didn't have a RFB so I told them to line up the yellow dots to the stems. No vibrations @ 80 mph so that's good enough for me.
