I have stage IV.... Very streetable.... But for your setup, I would suggest the Stage III... I've driven two hatches w/ B16's and that clutch, and for the streetability, I'd go w/ that one... But if you POUND on it and decide to throw on more parts, then Stage IV is a good buy..... I've got CM's 8ish lb. flywheel in mine, and It's nice....
