Ive been searching for some time and i would like to upgrade my brakes because of the upgraded power and weight coming soon in a few months, i would like to upgrade the front brake but they need to fit under a 15" wheel, also i would like to get rear discs, what should i buy for the front? And where can i get everything for the rear drum-to-disc kit? I do not want to pay an arm and a leg for everything, also i would like to do the front before the rear.
