heh, s'all good integra-r
i'd like to learn double clutch as well
but what bothers me is that, how you would do this so fast when your draging??? or maybe my feet is too bloody slow
but i wouldn't mind learning/praticing on my car. or at least see someone do it anyhow. i don't know much poeple that drive stick.

well you dont double clutch when you are upshifting, only on a downshift. so during a race you might only need to do it once to downshift to get the right gear (assuming it's a rolling start) and then from there you are only upshifting so you never double shift again
integra-r>> what you are doing is not double clutching, you're rev matching. that gives you a smooth downshift but it doesnt save your synchros from extra wear. the reason is in the article (and quote) i refered to in my previous post.

nautica_t - it's for downshifting when you're trying to get extra power not when you're coming to a stop... you can double clutch when you're coming to a stop but you can just use your brakes... like i said before and i think SiR Racer said too, it's used in turns etc, or in a race that might happen from a rolling start.... you wouldn't use it drag racing, cuz you don't downshift to gain speed there....

i try double clutch today, and it work out much smoother than just touch the gas and release the clutch. i will do it from now on.
if u want a faster stop, i personally think downshift and hit the breaks at the same time is the quickest way to stop.

oh okay, i'm getting a better understanding now than. So your basically saying that double clutching is mostly used when trying to overtake (easiest way to put it) another vehicle. that's the vibe i'm getting alex.
thanks.
thanks.

From my personal experience and from what I see on TV there is no need to double clutch, unless your driving your Mack truck down a hill. Double clutching was more a truck thing, up shifting and down most truck drivers would do this. Nowadays with the technology in gearbox design has inproved you no longer need to do so much work.
Heel toe breaking and shifting will smooth out breaking and down shifting. Most driver when coming to a stop or a turn will start to slow down and then find they want to shift to a lower gear so this means lifting you foot off the brake pedal and bliping the gas and then bake on the brake(you just upset your car. Now me or a few of you people will heel toe this is good because when you do this the revs come up quik your in the gear you want to exit the turn with and your car is HAPPY and so are you because if your car didn't come with ABS and it is wet or snowy out you just locked you tires up and are sliding.
PS. At an Auto cross you may find your self shifting to second this obviously isn't difficult BUT the second you come to a hard corner that reqiurs you to be in first(most Civics) you may have a fight in your hands.

how come so many people think that heel-toeing isn't a form of double clutching..... it's just a different way of doing the same thing you're just using the breaks as well.... it's what they do most often...
you don't double clutch when you're upshifting...
and no matter how advanced your gear box gets nothing is better than a human operating the machine you can let your synchros do the work but 1)you'll wear out your synchros and 2)you won't get as an effective response from the throttle as you would if you properly double clutched.... double clutching isn't for slowing down......

"hmm
hey soloz, you autocross??"
Yes alot.

I hear what your saying, What I meant was truck divers would sometimes do while upshifting. I don't understand what you mean by "you won't get as an effective response from the throttle as you would if you properly double clutched....".
Here is a question for you, when your on the road in fivth gear and you notice something a couple KMs away and you want to start slowing down. Do you double clutch from fivth to fourth or do you just go straight from fivth to four with a little blip?
I think the biggest thing hear is you want to match speeds, double clutching is the best if not the only way to do it but when I am driving down town I don't need to have my car out of gear and thinking about clutching and shifting back into gear. I don't know if anyone said this but you are trying to get all three shafts in your box to the same speed.

I understand the concepts, but find that the stock pedals on my car are just not designed for proper heel and toe action - I'd have to have my size 8 right foot pointing at my left foot to even come close to having my heel on the gas, let alone the bottom right side of my shoe!
That being said, what's a good aftermarket pedal/cover? I bought one set from my local dealer, but found it was too long at the bottom end - would dig in/stick to the floor mat...
cheers,
dave

If your foot is wide enough you can cover the edges of both peddles and rock your foot onto the gas. This is how I have learned to do it, I am too big and lazy to try and crack my ancle. Or depending how the peddle is mounted you might be able to pull the gas over a little bit. I saw this method in use on a brand new Miata at a dealership I work at(Sales manager was a track guy and taught me the other method)
