Question Racing Techniques

I have heard of the terms "granny shifting" and "double clutching" from the movie fast and the furius.

I had heard of double clutching before but nobody could ever explain what it is, how you do it, why you do it, or why you don't do it. Can anybody enlighten me as to where I can learn some of this information?

Any good books out there bout this kind of technical stuff or are these kind of things just handed down from one person to the next? If they're handed down, enlighten me on double clutching please.

I know this has nothing to do with Evo's but I'm going to be getting one soon and if I'm going to the 1/4 track here in cincinnati, I want to do it right.

Thank you.

I cant really explain double clutching as I can't do it myself. But it involves clutching in, shift to neutral, clutch out, rev match to desired lower gear RPMs, clutch in and shift to gear, and clutch out again. Basically i hear its for older cars with weak synchros to rev the synchros up to speed with the correct RPMS after downshifting. in a evo you really dont have to do it.

On another note, doing the 1/4 doesn't require any shifting skills besides knowing how to shift up correctly. Downshifting is really if you are braking and need to go to a lower gear to get back into the power band. Which is usually in racing that isnt a straight line.

A little knowledge can be a dangerous thing.

You won't need to double clutch an Evo unless your synchros are going bad. I've been driving manual transmission cars since 1982 and the only two cars I've had to double clutch were old Porsches which had worn-out synchros.

The best way to learn is to take a classroom session at the track. They will walk you through all of the shifting techniques.

True, but it is not a bad thing to learn. I now do it out of habbit on all cars I drive. It is easier on the syncros and if you do ever get a chance to drive something that needs it, it is then second nature.

Never say never. You never know when you need it.

I just said never
