After literally years of issues balancing aftermarket wheels I finally have a smooth ride. The correct size for the hub is 63.36mm. I have tried 63.4 & 63.5 and both sizes still allow a vibration. I got the correct ones here. I also have a set from Just For Tires, but they are the 63.5 size. I got the wheels from Discount (MB GTS Wheels) in 18X7 1/2 with a 45mm offset and the OD of the rings is 73mm. I won't return to Discount as they said my balance problem was two bent wheels. They were just too lazy to make sure the hardware was correct.
If you're having a vibration issue with aftermarket wheels check the centering rings. They should fit tight on the hub.
