Does Anyone here know what gears I have in my IROC? I know the rear end is the original GM install. I would like to know what gears, it has, and is it a Posi Rear End? I would hope so since its an IROC, you would think it should.

3rd gen camaros came with every type of rear end you can think of, no matter if its and IROC or not. The best way to check the ratio is to look under the center console armrest, to find the list of RPO codes, copy them down, and put them into the decoder on this site. I'm pretty sure that most of the gear codes started with G, so start with those. As for it being posi, jack the rear end up and spin one tire, if the other tire spins in the same direction, it's a posi, if it goes the opposite way, its not.
