    Double D Clutch?

    I was talking with my dad today when we were out driving and we got into talking about sport/street racing and I asked him if he knew how to change gears real quick, and he said "ohh yes, thats the double d clutch"
    He didn't really expand on "the double d clutch" but i'd like to learn how to do it.
    I know some of you guys are ace drivers (I can't even drive yet!) so could ya just tell me how ya do it, i'm kinda interested!
    Thanks

    A quick google search implies that it's a mod rather than a skill/routine/whatever.

    Because modern gear boxes are better than they used to be, there's no need to release the clutch when you blip the throttle. This makes the whole process simpler and quicker.

    Shad is right.....unless the gearkit is borked OR its not got synchros, you're wasting your time...

    even a quick blip between gears is only usefull DOWN the box....and only then to smooth the rev increase and to keep the car settled and not suddenly get nose heavy.

    Is it still good to use on old Gearboxes, even if they have synchro?
    Mine has synchro on all but 1st gear, but anything that can make it smoother is a good thing in my book.

    No, no need to DD at all these days, it's a slower way to change gear.

    However, like Zak says a quick blip of the throttle when coming down the gears is a good way to avoid the nose dipping forward which makes things smoother. But this is not DDing..

    Fastest way to go through (up) the gears is flatshifting, but this is also the quickest way to kill your gearbox.

    On my '88 MR2, I when I do a double declutch it'll slip into second gear when I'm downshifting way easier, you don't have to wait for the synchro to spin the gears up so it slots into place with almost no pressure on the gear lever. I still don't bother though, because for every one time I get it right, there'll be three times when I fluff up the sequence and cause a massive graunch as I try to shove the gear in while the clutch is out etc..

    Rave..keep at it mate..cos if you have a ropey second gear its worth it.
    It'll become second nature...I still do it by accident a lot on downchanges. Just no need, but I do.

    I'm a big fan of shifting without the clutch.. I'm quite good at it actually - I can go up and down the box very smoothly if I put me mind to it.. deffo the quickest way to change if you're tramping on a bit

    On a motorbike it's easy; TBH there's no point using the clutch to change up under normal conditions. If you think about it, all the clutch does is isolate the engine from the gearbox; it doesn't actually do anything to the gears. If you take the pressure off the gearbox by rolling off the throttle, then the gears can just snick into place as easy as if you'd pulled the clutch in. Changing down without the clutch is a fair bit harder and isn't really worthwhile in any case.

    I've never been brave enough to try clutchless upchanges with a car (i.e. non-sequential) gearbox- is it safe?
