alright ive got 60/14b with 4wheel disc's and 42's. i tried the stock master cyinder and i had no brakes. i put in a master cylinder from a k30 w/o hydroboost, and now i have brakes, but they are not good by any means. what are my options now? is a p-valve going to solve my problems, or is there something else? im going to be installing new extended ss lines for the front, but i dont think that will make a difference. any help would be great.
