Won't the RPO codes tell you? Run 'em at www.thirdgen.org

Alright, I just checked TGO and B4Z is the option code for the IROC package. The list should be in that storage compartment in your trunk.

TGO didn't come up on thirdgen

When I said TGO, I meant ThirdGen.Org lol sorry for the confusion.

shwine617

lol thats my fault, i should of realized that
i don't see anything in the trunk lid, also did u see the code that tells if its an rs?
thanks

You know what I'm talking about right? That little compartment you need a key to get into? I forget what years it was but it also might be under the console lid. For an RS, all I can find that MIGHT be it is R1V: Appearance Package

I've got F41 (mine is an RS) and that's
F41 : SUSPENSION SYSTEM, FRT, RR, FIRM RIDE, HANDLING

I'm nut sure if F41 is just on RS's though.

First of all what year & what engine is your car?

xeroxed

check and see if it has a wonderbar connecting the 2 frame rails in the front. itll be just above the front sway bar and below the radiator support. if its a completely stock car then it should be a iroc.

If you cant find the RPO codes under the hatch area Try looking in your center Consol area. should either be on the lid or just in side on one of the sides. Make sure the Vin matches the vin in your car.

The option codes will be listed under your center console lid. Look for B4Z listed there
