Hmm, that doesn't make much sense to me, because when you go up in gears, you don't want to rev the engine, because the engine speed has to be a little lower. When you shift down in gears, you want to rev the engine to try to match the engine speed with the gear you're going into. RockinWRX explained double clutching correctly. The thing I don't get is this... why do you have to press the clutch in twice. Can't you just press the clutch in, shift down a gear, blip the gas and let the clutch back out? This is what I do, because it gets rid of the lurch when going down in gears, plus I think it saves the syncronizers a bit. Why do they say to let the clutch out, then put in neutral, then put clutch back in, then shift into gear, then let clutch back out again? Seems like your letting the clutch out once more than is really needed.
