Check the RPO's for B4Z. If the sheet is absent, check the door placard for 16" wheels, for the Wonderbar, for the pass side dash for the badge, for fog lights, etc.

RPO B4Z as stated and a picture of the dash emblem.

Re: IROC or Z28???

The dash emblem can be easily swapped, so it's not really a good indicator. The best is the RPO B4Z, but if the code is missing, look at the door placard for 16" rims. The IROC was the only Camaro to get that rim size. Also, fog lights were available on a level 3 optioned Z28.
