I didn't buy them to eliminate vibration. There's a better way to fix this. My story looks like this. New rims (MOMO Quantums) for my VW Jetta MK5 I loved it but there was terrible vibration. With some research and advice from several tire shops, we found that the stock bolts on my car had ball bearings, while the newer slap discs needed a tapered fit. only then does the vibration stop. So I went ahead and bought new bolts and these hub center rings but not for vibration but to be able to easily mount and mount the rim to the hub. Result ? easy assembly of the rim :) that's it. Please, before buying centering rings and expecting them to hold everything in place, first look at the type of bolts required for the rim.
