are u sure? cuz the last time i worked on a b15 it had the same calipers as my b14 on the front, and the rotors looked to be the same diameter too.so thats why im guessing the lines are the same. as long as the fittings bolt up i can make it work.im asking cuz im putting on stainless steel brake lines and i cant find any for my car except for some crappy ebay knockoff stuf,but i found b15 lines for a se 2.0.im also gonna be changing to nx calipers up front,not sure if that will be different.
