I have a 2009 STA and want to install later Explorer wheels on it. Has anyone done this with success? Here is what i see: 8Jx20 ET35 5x114.3 70.6 is the center bore. New Wheels: 8.5Jx20 ET44 5x114.3 63.4 is the center bore So what I am looking for is a spacer thats is between 5/8" and 1" that would have a hub centric ring that would be 63.4. If I did that, we should be in business, correct?
