yeah that makes sense, but are you really going to cook your brakes that easily? a good set of performance pads will work well under high temps! and if you can get your brakes to lock, then im sure you can get them to not lock, if you get what i mean! i'm not against big brakes btw, actually thinking of getting some upgrades for my 309, but what i am saying is that you dont NEED them, depending on how much of a tit you can be over an extended period of time...
