whats up guys, i just purchased,for the front 2 Power Stop Cross Drilled Brake Rotors and Axxis Brake Pads ,and for the rear 2 Power Slot Slotted Brake Rotors and Hawk Performance HP-Plus Compound Brake Pads, now, i was wondering would stainless braided brake lines make that much of a difference, and also, do i really need to upgrade the calipers, or if i could just paint my exisiting ones? thanks for any help gentlemen

The brake lines will tighten up your brake pedal like crazy, so with upgraded brake pads too you will be able to stop a hell of a lot faster. I don't see why you couldn't use your old calipers as long as the rotors and pads fit together properly with them.
