All depends on how fast you are going on cornering. Nothing can be done drastically to bring the GTO down to 1360kg or less from its factory weight of 1725 kg. So even if you strip the entire car down to the frame and make it a all wheel drive go-cart still wont work, light wheels, deleted engine components, perhaps remove that super heavy rear wing!! 
still wont work, I dont understand why people just cannot except the fact that the weight problem is not the tea but the cup that holds it, am I right?
Thanks more pics coming soon
Hey If I can bring it down to 1500 I would consider that a success!
Anything is possible if you have the money
