Double Clutching
Double Clutching
I have heard so many different storys on what double cluctching is, Does anyone here know the correct way to do it. One of the storys i heard was. you push in the clutch take it out of gear release the clutch then press the clutch in again before putting the car into the next gear.
Exp. 1st gear to 2nd gear
1st gear push in clutch bring car to nuetral release clutch. press clutch place car in 2nd gear release clutch.
Is that the real way to double clutch? and if so whats the point behind all that

Dont rely need to do it on cars now day's with syncros. Back in the day to do a quicker shift move you would have to depress the clutch pedal twice to help slow the tranny gears so the car could change gears more effiecent without grinding.
Basically double clutching is used when driving Trucks. The double clutching phenonom started with vin deasels line "granny shifting not double clutching like you should" Fast And Furrious line. it is caused by people not realizing that the double clutching part of the quote is scarcasm and Vin Deseal (Dom) bassically saying you shift slow and you might as well be driving a Mac Truck (or something along those lines)
Ricers that think they can drive and actually no nothing about cars thought that it was a technique for shifting when racing. This is wrong.
Now you know and you can tell anyone that wants to learn how to double clutch to go to truck driving school.
note: Double clutching can be used in Adverage cars when shifting from second to first at low speeds. There is usually no syncro for first gear and therefore double clutching is nessessary to do this. You would use this for instance in an auto cross event when you have a really sharp cornor (where your speed will be below 30km/h [not sure the mph Iam Canadian] to keep your revs up and be able to acellerate out of the cornor while not droping below the power band. This can also be done by rev-matching which is reving your engine before you let the clutch back out to match the rpm's to the estimated RPM's of the lower (in this case first) gear.
I hope this clears up all the confussion.

My one buddy has an s2k and 2nd to third grinds when he is high in RPMs. when he just powers shifts, the gears will grind, when he double clutches it, the car will shift good. correct me if i am wrong i dont know much about double clutching but wont it let the cincros have more time to work?
It could be that your friend:
a)Is beating the syncros. Not that probabal but I used to do it all the time in my buddies Miatia
b)The syncros and or gears are going in his car
c)He isnt driving correctly and is trying to shift faster then his foot works (for the clutch)

double clutching is NOT downshifting. finally someone else who knows about his besides me.
Hell toe is similar but not the same.
When heel-toe downshifting, say you are in fourth and coming into a steep turn and you want to have power coming out of it. Heel-toe is used for two reasons, one (main reason-to be in the proper when going through and exting the turn, to be in your power band basically), and second to help slow the car up.
You're in fourth gear going 110mph at 6900rpm, obviously if you were to drop it to third right now your engine would go boom. So you let off the gas (obviously) and start getting on the brakes, as you are slowing down to say 80mph, you're right foot (the one thats on the brakes) rolls or twists so your HEEL is touching the gas. At this point while still braking your left foot presses in the clutch. You then press the gas to rev match while the toes of the ball of your right foot is still on the gas. As you are slowing down from 4th gear to say 80mph your rpms are at 5000. Obvoiusly in third gear they will be around 7000. So you can't just dump it into gear. By pressing on the gas with the clutch you are getting your rpms set to be ready for the lower gear. You are shifting and brakign at the same time. When you get your rpms about right you shift your wieght of your heel and release the clutch. If you did it right you will snick into gear smoothly with no jerking. I hope i described that well enough for people to understand. I can do it better speakign and even better in person. Very useful in autocross and roadracing

For us front wheel drive car owners heel-toe is a great way to prevent that nasty understeer. By covering the brake (lightly) when cororning while staying on the gas you can hold a very tight cornor without/with little understeer. When I do it I use the left side of my foot for the brake and the right side for the gas. This is very easy in the lancer because of the pedel positon. If you have pedal covers it helps even more.
Heal toe can also be used in any application where you have to stop fast and dont want to dammage your clutch.
Senario: Say your approaching an intersection and the light turns yellow. There is a cop there so you want to stop to avoid any possible hassle (basically referning to the point of no return).
If you heal toe to beake and downshift at the same time you will stop much faster.
I would suggest practising to perfection before trying in areal life senario first.
If it isnt working ofr you or you cant seem to grasp the hang of it then just dont bother. But what do you have to loose right.
Next time you approach a red light. Stop very early and use the heal toe method. As you build confidence with the pressure to use on the brake and how to hit the gas at the same time, start gettting closer to the intersection when stopping untill it becomes the way you drive.
thats also correct. The FWD owners that are corner workers cover and feather there brake to keep the front end tucked in the turn just as you said to prevent or help decrease that nasty time scrubbing event called understeer. Finally someone who knows the difference between heel toeing and double clutching
