All GT's came with traction control, but not all have the traction control off button. Try doing a burn out, if you have a light on your dash come on that looks like a tire that is your traction control activating. The only way you can turn it off is by buying a tuner and disabling it inside the computer, but keep in mind it will ALWAYS be off, so if you run into a little water or rain well you won't have that extra insurance until you turn it back on.
03 Zinc Yellow GT. With enough bolt-ons to really have some fun.
