this is the first time ive heard double clutching defined, whats the benefit to that? on a side note i did power shift my zetec to a 16.3 recently and i fail to see how doubleclutching can improve upon that. maybe its a road racing thing. all i have now is opt. tb, cta intake, msd coil, redline trans fluid, and muffler delete option with turn down (saws all). cant wait to get header, custom exhaust, cam gears and a chip.
