I have just recently purchased a 99 Eclipse Rs, and I have asked many people in my town on how to double clutch but I dont really believe they know what they are talking about. I think this would be the best place to find out. Will someone please explain to me exactly how to double clutch thanks.:thumbsup

Ok Brian Spilner ;)

Double-clutching is the right way to downshift at a high speed and not place excessive wear on the trannys synchros. It lets you go down to a much lower gear without the tell-tale lurch you normally get when the clutch is let out after downshifting

Have you been "granny shifting, not double clutching like ya should?" hehe :P

i got told by a guy i burned (he was driving a civic si) the other night that he only lost because he wasnt double clutching...

Double clutching is used only when downshifting, and wouldn't make a difference in race. Especially if you raced from a dead stop. Anyways, to double clutch, say your crusing at about 60mph in 5th gear. Push in the clutch, shift to neutral, release the clutch, hit the gas and bring the rpms up, push in the clutch, shift to the lower gear, release the clutch. All this is done much faster then it sounds. If you do it right, you'll notice a much smoother downshift.

You can double clutch while upshifting or downshifting.

With cars today there is no point in double clutching unless your synchros have gone bad. That's why you have synchros, so you don't have to double clutch. And there is no point in saving wear on the synchros, since for normal driving and with proper tranny maintenance synchros should last quite a long time.

So, unless you are driving a 1950s packard or studebaker, or you lost a synchro, don't worry about it.

I never understood the "double" part of it. Couldn't you just leave the clutch in the whole time? The definition of double clutching says you clutch, shift to neutral, rev, clutch, downshift, go. Why can't you just clutch, rev, downshift, release clutch, and go? Were you not able to do this in the older manuals or something?

all i do is push in clutch in one step and next step is rev adn downshift at same time, VERY smooth shift! 2 step process

FAST AND FURIOUS STYLE!

all i do when i start in first gear onnce i get to 3k rpms i hold the gas and slamm the clutch to the floor to give it some pick up..i do this also gonig into third if i am racing or if i am bogging down in a gear say if i am going 60 i cant shift into second for a down shift i shift into third and then hold the gas as i am going and slamm the clutch down...im sure this is bad for everypart of your car and i cant spell so dont mention that stuff. hehe

you do it 2 times because on old clutches you had to do it 2 times to get the synchros to line up straight.

hey guys, back off. i dont recall him commin on here talking all F&F shit. he asked a serious question. if you dont have anything good to contribute to the question just stfu.

No...

The reason you have to clutch and switch to neutral have the clutch released when you rev the car is the hole point... to get the internals of the tranny up to speed. If you were just to rev w/ the clutch pressed in your save your clutch but not the transmission, when correctly double clutching you heavily save wear on both the clutch and transmission when downshifting.

yeah double clutching is pretty much what they said ^^^
but while it may or may not save wear on your synchros an whatnot i do it because you get a smoother shift and no jerk. the saving wear part is a bonus:thumbsup

It saves wear on everything (clutch, syncros, tranny gears, etc...) if you do it just right you won't put virtually any wear on your syncros, because your not using them.

yep its for a smooth transition into the lower gear. It helps prevent wear and tear on your tranny and clutch. It also helps you entercorners at precision weight balance. Notice when you downshift and dump the clutch the car jerks violently, this upsets the cars balance. I've been explaining this way too much I'm sure you coulda found this using the search engine.

THe other method of smooth downshifting is heel and toe. That is when you rotate your foot from the brake pedal while braking and blip the throttle with your foot. Its a much quicker and more difficult motion than double clutching which makes it better while cornering.

A Mercedes mechanic of at least 20 years experience told me this exact same thing. Double clutching is only with cars that have bad or no synchros.

i got told again yesterday i needed to learn how to double shift... i was about to race and was like 'nah you will prolly win ill blow my launch', 'well dude you need to learn how to double shift you will do better on your launch'.

First remember that 90% of the people who race on streets are idiots. (not saying its because they race on streets but because thats really all they do) They dont know anything about real racing. I have discovered that many people call what I call "power shifting" (Never taking foot off the gas when shifting) Double clutching... Makes no sence... And not to bring up F&F but none of those damn kids, the ones who think a tree is a stop light, you hear say anything about double clutching knew those words before F&F. I would suggest next time you see the idiot you ask him how to do it and listen to the lack of knowledge pour out of his mouth.

On a side note I cant wait till 2F2F to come out on june 6 so we all can have another big laugh.

i did ask him, but i didnt quite follow his instructions they didnt make sense hehe. kinda like 'do this, but do that, and do this while you do that, and you should shift and knock like 4 secs of your 1/4 time) and yes he really said that
