I went to my wheel guy today to order some TSW Nurburgring wheels in the stock factory wheel sizes. He called his TSW rep, and the rep said that the Nurburgring wheel wouldn't work on the Boss because the center caps would not clear the factory grease cap. The rep said I might have to run spacers if I wanted to run center caps on the front. I call BS. I'd like comments from those who are running the Nurburgring wheels on their Boss.
