Those offsets will not fit a Camaro. Boss really f'ed up and should have done their homework, but a 9.5 wheel needs at least a 5.5" backspace, and with a 5" backspace they'll rub the outer fender. Don't waste your time and money with wheels that are not going to fit, I recommend spending a few hundred dollars more and get your self a set of Foose or Vintage Wheel Works that fit.
