I found an article that theaches these things > how to change gears faster (when to change eficiently) - exercices, and it also teaches you something called the HEEL AND TOE DOWNSHIFT > can you do it???

You can find the article here...

I almost got it...

 

heel and toe-ing is pretty familiar to most people on the board i think. No one should be allowed to drive a manual, or at the very least, downshift, without learning how to heel toe.

 

for me it isn't as much heal and toe as it is left half of foot on brake and right half on gas to rev match, same concept though (Go, size 13 feet !!!)

 

guack, same idea, except some people may not have as big a foot as you

 

thats exactly what I do. Its a great technique for cornoring at quick speeds too. That way you don't get understeer. (problem with FWD cars)

 

+1

Size 13 also

 

Too bad these big feet make it hell to drive some classic cars (old porsche 356 )

 

What about double clutching ?

 

there is 3 techniques to minimize synch gear wear and to minimize imbalance from any shutters or lurching..

1. simple double-clutching is what you guys are describing... you clutch and push it to neutral (release clutch) followed by reving to the appropriate RPM.. then downshift.... unfortunately this method requires alot of time even when done fast because you cannot brake in this time...

2. heelNtoe is double-clutching combined with braking.. your right feet brakes and immediately left feet clutches then you neutral... release clutch...and you rev match (you are still braking) with the heel of your right feet while the "toes" of your right feet is still braking... after rev match you clutch with left feet and downshift...... the major advantage to heelNtoe then just regular double-clutching is you dont throw off balance by braking then stopping to do your stuff... you stay ON the brakes and keep balance... another reason is if you want to go fast, you brake late and you brake smooth, not an on and off switch like you have to do if you didnt heelNtoe...

3. single clutching - i'm not sure if this is an official name but this is what i call it.... its heelNtoe but you do this when theres very little time or your going under 40mph and dont feel like going through the full heelNtoe..... (but still better then regular double-clutch).... you brake with right and clutch with left... now WITHOUT letting go of the clutch, you downshift, quickly rev match with the heel of your right, then let go of the clutch as you gas.... you should master heelNtoe before you do this because if you hold onto the clutch too long, you may wear out the clutch throwout bearings..... but i love this step because its simplier, takes about half the time of heelNtoe and timing the rev match is alil easier too....

i use all 3 of these methods naturally daily.... it reduces synch wear, makes you faster on the street, and makes daily driving much more fun.... oh also you are kinda practicing if you want to hit the track or autoX in the future....

 

I never double clutch. I just rev match on downshifts while braking.

 

the whole double-clutching thing is soooo tired. modern synchos make it a waste of time. let it go people.

 

Me neither, why would you double clutch with synchros? I heel-toe, or rather, side-of-foot-toe, every time i downshift while I'm on the brakes. I put an adjustable Razo gas pedal cover on my gas pedal to enable me to do this (small feet).

 

double-clutch is heelNtoe without the braking....

 

Just because I can, and becuase it is fun and when I get it perfect and fast it feels rather race like. I don't use it while I am racing though, I rev match but double clutch is too slow and too much to think about. I also tend to use the gears a little more then a lot of people seem to so I double clutch when I can just to make sure my gearbox lasts, and if I do crunch a gear I double clutch for the next few changes to teach myself a lesson.

Very good Explaination

I was arguing with my cousin about the proper way to do a heel/toe. I've learned how to do it in this forums few months ago. But, my cousin said that he never heard of releasing the clutch while doing a heel/toe... He said all the professional driver do a single clutch heel/toe because it is alot faster compare to double clutch heel/toe. I told him it saves your clutch from wear out, easier to down shift 2 gears ... and he said with the current synchros technology, double clutch is useless, slower, and harder to do ....

I know double clutch heel/toe is the proper way, but I don't know how or what to argue back....
what do you guys think.
