My buddy asked me a question tonight, and I couldn't give him a good answer.

His question is basically why double clutch, when you could just keep the clutch down, "blip" the throttle to the rpm you need, then release the clutch.

I know double clutching isn't really necessary because of synchronizers, but as long as you are rev matching, is it really necessary to do the clutch action twice?

Thanks for the help.

This is a long and heated debate. Do some searches, you should find what you're lookin' for.

To answer your question, no.

to save wear and tear on the synchros/gearbox...and if you ever have to drive a non-synchro car in a life or death situation - you'll be all set. Like if you were being attacked by a killer clown near an old stock car or something...

No need to - just keep the clutch in. I learned and have been double clutching as part of my Heal and toe downshifts for about 6-7 years, but it came back to bite me. Late this year I needed to downshift in an autox but the braking zone was really short, and found that I could not get an effective downshift with dc and - oh horror, my timing was off for the heal and toe just holding the clutch in. I've recently been practicing NOT doing the dc just to get my timing back.

It's not really necessary to do a dc on a modern tranny - though sometimes if you're going for first, it's easier double clutching. It's still nice to learn as a skill - just gives you an idea of what guys like Fangio had to do back in the old F1 at the N

I only double clutch when im in a higher gear and I dont feel like downshifting. It gets me a little bit faster pickup then just just flooring it if Im not in the rev band.

I double clutch if the RPM is gonna jump high. Or if i have to back up my car.

NO. Unless you just watched Fast and Furious and want to be a retard like Vin Diesel.
