How to dubble D clutch

[lamason]

What is dubble D clutching and how do you do it?
Thanks,

[RS13]

Ummm.. what?

[NZ_AE86]

Why? you will never need to do this!
It is when you push the clutch in and change out of gear into neutral and release the clutch then push the clutch in and select the next gear and release the clutch.

It a load of bollocks to us car driverer dudes! I've heard sum ppl double clutching up the gears as they leave caltex

Important techniques:

Not crashing,
Heel/toe braking,
Driving within not just your limits but everyone else around you, don't expect grandma to know what to do when you slam it into second round a corner and drift past her.

Feint drifting in a fwd (Not that i can do this at the moment cos my engine did die )

Errr.... I fail to see the point of it! You could cut out some of the steps by just pushing the clutch in, take it out of gear and put it into the next gear without releasing the clutch... Like normal people!

sorry to sound dumb, but why use this technique? what's the benefit?

[fangsport]

it's somethings necessary in trucks and when the syncros are rooted in a car.

[Chickenman]

A pre synchro mesh measure for shifting down the gears...... Truck drivers still use it, surprisingly enuff...... to drive trucks. Do a search (I can't be bothered) Ppl much more on to it than me have talked bout this in depth

[fangsport]

the down shift method is to clutch in, pop it into neutral ,blip the gas to match the revolutions the motor will be doing in the next gear then clutch in and select the lower gear. in non-mesh boxes, unless the revs are matched, it is virtually impossible to change gears.

You have no need to learn how to do this, or a reason to use it in everyday driving

it's far easier to blip the gas while clutching when trying to down shift, but even that is only neccessary if you have a fully straight cut box , and only done for 'wank value' if it's a fully synchromesh.

[Crimson Tears]

It's actually a very useful technique if you have to drive a vehicle that has a gearbox with $&#$% syncronisers.

[Stealer Of Souls]

Yes... tired sychro that won't last much longer.... Sounds like my poor box.....

Double de-clutch is only for cars with tired/no synchro or for those aspiring to be race drivers... to practice for when they have a car without synchro....

In my opinion... if you're learning to heel-toe then you might as well learn double de-clutch since they have the same end result. Matching revs on down shift.
I use them in daily drive... For me it's all about preserving my synchros for the up shifts... They're already sick enough... Tee hee... and I can trash them with flatshifts instead....
But seriously... if you drive your car hard then you should learn heel-toe first and then double de-clutch, and then get used to flatshifting (and the horrible sound when you stuff up)...

Heh my downshifting must be all wank factor

when changing down, its clutch in, blip throttle, shift down, then release clutch, works perfectly 90% of the time

[badidas]

real resason it started was because back in the hay day the old boys had tod o it too change gear because syncromesh gearboxes didnt exist

most trucks these days dont need to be double de cluched unless the clutch or gearbox is ferked most trucks chew through 4-5 gears form 0-50 kph imagine double clutching through 16 gears

haha i havent quite mastered it cos im not quick enough, darren has to do it in my car cos my 2nd syncros are absolutly gone.

i do the bliping whilst upshifting, cos i cant flat shift into 2nd, so it just keeps my revs up that extra little bit that it takes for me to change into 2nd.

other than that im a total wanker and do it for that reason

[deaf_rattle]

first you open your hand and then squeeze

yeap, i must have the smoothest and quickest shifts of anyone who has driven that car (evil evil 4age box)

At speed i find it quicker to (heel-toe) double de-clutch when I need to downshift, when you get reasonably good at it then because your rev matching you can just pop the clutch in and out rather then having to carefully let out the clutch (where the car is engine braking and can get upset)

[Rollux]

I heel-toe on all down shifts in the 'dore as otherwise I'll lock the inside wheel when turning, and i'm sick of doing skids to get rid of flat spots...

Mind you, the diff is shagged also.

But newer cars with clutchless manuals all blip the throttle electronically to match revs to prevent shift locks. Sounds good too if matched right.

[Chickenman]

IMHO:You should always match revs on downshifts....... think of your clutch.
