Im running ATS Cups so its not for looks that im thinking of fitting them, coz you wont see them. Im running a 2.0 16v on 45's, head, cams, blah, blah......So i was figuring that a horsepower hike would benefit from a brakepower hike. Does the rear disc set up really make such little difference?? I was thinking 'good enough for vw etc etc' but if its gonna be no better than properly set up drums i wont bother. Any other comments please.......
