On an average car, yes better pads will make it stop better, half the problem is the overheating, those take ALOT longer and ALOT more pressure to stop them vs. the regular rim, that little ass rotor and cheap caliper ect. arent going to perform the way somthing bigger/better would do.

also, what about the problem I See when there driving down the road and cant even keep the shit strait. the car tries to follow the grooves in the road instead of going where you tell it to go, do you know what would cause that?
