practice practice and practice
another good way is to get those driving steering wheels with pedals and shifters for computer games if you too worried about destroying the car.

Take it a little at a time, and build up to it. Just like learning any other coordinated activity...do the easy ones slowly til you get the hang of it.

For an easy practice piece...

On a road by yourself: Drive at 3000 rpm in 4th gear. Try a downshift to 3rd, which would put you at 4000 rpm. Feel free to watch the tach as you blip the throttle and make the change. Take your time, feel free to work the throttle slowly and hold the rpm rather than just a quick blip.

Spiral out from there.

Arun,

Just be gentle & smooth while practicing, and try not to lose your temper with the car if you make a mistake... The more aggressively you try to push yourself upon learning, the greater the chance that you'll be punishing the car.

Just remember: Smooth & gentle while gradually and slowly picking up on the skill. It takes time, so just keep your patience. If you keep that mindset, then you won't be punishing your car as much as you're thinking right now.

Good luck.

When you get adept at it, the steps become somewhat blurred. The clutch does not have to come all the way up when in neutral - just enough to spin the gears up to speed. The last step, to have the revs match on the final clutch engagement, is very important. Otherwise you'll have a jerk either forward or backward. Not good if you're racing, and embarrassing on the street if you have a passenger.

There is a really good quantitative description of double clutching in Piero Taruffi's book "The Technique of Motor Racing."

Well, I always heel-toe while driving around town(Made it a habit with my old car, learning the technique, for the practice, now I always do it, unless I'm coasting to what I know is a stop for sure.), I'm just trying to figure out how I'd incorporate double-clutching into that, haha. I doubt I would, I'm just trying to go over how you'd do both together, because I'm imagining that'd be the only time to do that, aside from while accelerating, since you don't normally drive around shifting gears while maintaining speed.

I'm just being interested is all, trying to play through it with my head, but thank you.

Go to the library and check out Taruffi's book. Or hit Google and watch one of the dozens of videos.

Ok, it sounds like you might get somewhere with this.

You're at the stage where you need to learn to downshift so you can get good acceleration, right?

Since, you said you tend to accelerate, then, you are catching it right for that downshift.

So just practice downshifting with the immediate acceleration and you're there.

Downshifting to brake is very hard on clutch, trans, and just plain not necessary, unless you like to beat your car on the track for last .1 second.
