Hey guys/gals... Im about to replace my brakes cause they are bad now, im not planning on upgradeing, so no Baer recommendations please!

Anyways, I think im going with all BAT products, the rotors and pads will be their "$175 Brake Special" and I will be putting on their Stainless steel lines, and Wilwood fluid. Couple of questions, first of all, I obviously dont want to be downgrading my brakes from stock, I want to keep it on par with stock. So if you think I will be downgrading, PLEASE let me know. Also, how much brake fluid will I need? Thanks alot for all the help as always!!! -Nick
