So I am finding this to be a bigger issue than I had thought it was going to be and I am not sure if I am missing something.

the hub on our cars is 57.15. The bore of some Rotiform wheels is 70.68. Now because the wheel is ball seating and not cone seating it is very important that the wheel be seated pertly in the center. There is no hub centric rings that are made that are 70.68 even from rotiform. I purchased 70.00 mm outer hub centric rings and there was plenty of play in the wheel. I called rotiform and there response was to put electrical tape around the ring.....I get why but just doesn't seem right and ever since I have put these wheels on I have had a horrible vibration 55-70 and again at 85. Trying to figure out what exactly everyone else has done. Thanks
