88 IROC question
Other than cosmetic differences (emblems, paint, hood, fog lamps, and taillights), what mechanical differences are there between my '88 IROC and a similarly equipped sport coupe? My IROC is equipped with LO3 305 tbi, 700R4, and 15" wheels with rear drums. Are the sway bars, springs, steering box, or anything else different? Thanks

Yes, the IROC should have bigger sway bars, stiffer springs, and better shocks than a Sport Coupe.
