I have a chance to buy some Kinesis or Corvette Zo6 wheels but i'm not certain I have done the math correct to determine if I need spaceers. Can anyone help double check my math? My reasoning behind the math is to keep the center of the tire in the same location as it sits now. Let me know your thougthts.
