Bigger brakes bring their own problems, I have seen the entire beam assembly ripped off and tucked under a chassis, show is one thing but stuffing 'big' discs on requires some kool math to get the 'bite' right, unless you want to leave the road kinda sudden, xase of two much of a good thing. Many 'sports' cars have rotors that don't fill the wheel, my own Cosworth for example.
