Amateur Question about Double Clutching
I want to understand this better so I figured I'd ask here. My question is, what is the point of going into neutral when double clutching? Why can't you just match revs with the clutch fully depressed and then just it out? How is that really any different then fully depressing the clutch, throwing it in neutral, letting out the clutch, then depressing the clutch in again, match revs and release? What am I missing? It just seems putting it in neutral is a waste of a step.
Thanks in advance for any explanations.

When the clutch is depressed, you have no input from the engine to the transmission. By letting it out in neutral, the engine brings the internals of the transmission up to speed.

From what I read that's more of an explanation of rev matching. I thought double clutching is used in cars that have transmissions without synchros. Someone correct me if I'm wrong.

You are correct. From the way I understand it, double clutching is unnecessary in modern trannies with synchros. Rev matching is all you need to worry about.

The only time I double clutch in my Z is when I downshift 2-1 or shift into reverse. Most people don't realize they are supposed to double clutch in those situations... but they wonder why it clunks, grinds or won't go into gear.

since we are talking about heel and toe downshifting too. i think the gas and brake for me are too far apart to use the side of my foot i find my self heeling the brake and tapping the gas with the ball of my foot does any one else do it like this. i need more practice though i wanted to practice on my last track day but i was so caught up in the moment i just didnt think about it i found my self with the clutch in more than i should. any body have any good pointers besides just more practice?
