    Double Clutching?

    Hey guys,

    I was just wondering if double clutching is used anymore. I know what it is... When you press the clutch in to shift into neutral, then depress the clutch. Then press the clutch back in to shift into your next gear.

    Does anyone do this anymore and is it needed/ beneficial? I know it's supposed to be easier on your gears etc. Should you do it with newer cars, trucks, or was it mostly for older vehicles?

    Most people just put the clutch in to shift out of gear and into their next gear.

    Thanks for your help!

    If you know what you're doing, of course its easier on the vehicle. When driving a manual I find myself doing the double shuffle - along with heel & toe on the downchange - pretty much all the time, just instinctual and 'force of habit'. And its fun

    ive taken to the double clutching coupled with heel toeing on my rx-7, it is required to downshift as the synchros in 1 and 2 are non-existent. in newer cars its really not necessary, but not bad for the car.

    Fun and when you're really going for it, it helps to not lock the drive wheels.

    Considering I rarely hear of broken or damaged gearboxes (apart from some LOL GT-Rs ), it's probably pointless in non extreme cars.

    The clutches of the first generation of common rail cars were already quite stressed for the higher torque and probably a lack of proper development or the use of older turbo diesel clutches, so maybe double clutching could've been even worst for them...?
    just a guess.

    Used to be not uncommon (particularly in japanese cars) for the 2nd gear syncro to clap out well under 80,000 kms

    Even recently I've encountered everyday cars merely 7 y/o but with tired syncros, so not necesarily pointless imo

    Ditto.

    Also certain cars with a lot of torque/HP have very stiff 'boxes that need to be double clutched when cold.

    could it be due to poor usage rather than not double clutching?
    Pointless was perhaps a bit too much, but I don't see it as a necessary thing on a new Fiat Punto (or even an used mk1 one), for instance.

    hhmm
    never heard of this technique though
    i only had one car which was manual and that was a E36 325i coupé and i never used this technique but i never had any trouble with the gear box... even though it had 250.000 km on the meter

    if i ever have a manual car again i will try to use this technique

    dfh, for normal driving it is unecessary to double DE-clutch.
    ONLY a benefit when driving VERY hard and desire to keep the car balanced on entering corner and readying for acceleration (hard) out of it.

    i've heard that double clutching on a regular car with synchro's in all gears, its pointless to double clutch. heel and toe is still very much used. i've never double clutched since i learned on the civic. i rev match downshifts but never double clutch. works fine for me. i know on older trucks and cars without synchro's you have to

    I must admit, I had not heard of this technique before.

    Cue Falcon 1983.

    Extremely stiff box when cold etc. Just reached 241,000, you think it'd be an idea to try?

    Anyone care to elaborate on heel-toe? I know its braking & accelerating with right foot but other than that
