I just put the stage 2 on my car this weekend and ordered the alum flywheel to go w/ it. The problem was that Spec sent me the wrong bolt pattern. In 00 ford went to an 8 bolt pattern mid-year, and I have it, spec sent me the 6 bolt. So I had the stock flywheel turned and the guy who did it said with my car being a drag racer and not a scca car the stock flywheel will hold better rotating mass= better launches. So in any event, the alum flywheel is getting sent back b/c I have the LT's now, and i dont want to take that trans out unless absolutly necessary.
