What you're neglecting to realize is that a Supra making nearly just as much HP as your Lambo is about to(And probably weighs even LESS), can't even touch the UGR cars. At those power levels you need the AWD system. By the time you even get 1600+ to the pavement, the UGR car will already have a nice jump on you.
I'll let you continue bench racing... I'm in for the video between you and Jamie at this point.
