Mount your wheel, but before putting any lug nuts on, if you move the wheel side to side, do the walls of the holes bang into the studs? No, they don't, because they're already centered.

I do agree that it's better to get the ones from Courtesy, now that they're finally available (I got my McGards before the 'real' ones were available). If you've already got the McGards, however, I see no reason to waste your money on ordering another set from Courtesy. I've had mine on for 4 months now without any problem whatsoever.
