Well your skepticism is wrong and I guess since you rather post without proof ill post for you. You can even look at images of the underside of a 33 GTR and a GTS(T) and see a clear difference between RWD and AWD.
Thanks for the post, I learned something about the difference between the chassis. I wanted a track GTR but, couldn't see myself spending 25k to wreck a beautiful car. Ill wait and see if anyone stateside has the pockets to pull it off.
