IROC-Z and Z28 suspension differences

I have an 82 Z28 and an 88 IROC-Z and was just wondering what the suspension differences are. Does anyone know what the spring rates are?
Thanks,
Will

dont know on the spring rates but really only the wonderbar, bigger wheels-tires, and then just tweaks to the springs/shocks/alighnment. other than that it was just bigger engines with extras removed to save on weight.

so asking out of pure curiosity a 4th gen firebird WS6 is in theory a IROC level car? even if no what were the equivilent levels of firebirds in relation to the camaro? such as SC - firebird, formula - Z28, TA - IROC? did i guess right? or did the firebird even have a IROC level car? i dont know the birds real well.
