Double-Clutching VS Granny Shifting

[Allanon1313]

Ok so I've been "granny shifting" since I bought my car and I've gotten to the point where I can shift rather fast. But I hear that Double-clutching is supposed to be faster in a drag scenario. I've practiced double-clutching and still seems as though "granny shifting" is faster. Can anyone tell me why and/or how double-clutching is better? I don't see the point outside of preventing wear on your clutch/transmission.

Ok to really become a better driver:

3. See points 1 and 2

double clutching is required only in cars with no syncros. All modern cars have syncros therefore it will not be required to double clutch unless the gearbox is bad in which case you don't race.

also there is no such thing as "granny shifting" unless you use in a derogatory maner with the clear intent of insulting someone else's shifting skills.

95 grand am... it definitely has synchros... don't worry about double clutching. If you were downshifting you can start with rev matching... that does help the tranny.

there is such thing as double declutching though which is described here http://www.tcsracing.org/heelandtoe.htm

[sidewayzS13]

but as far as double clutching as portrayed in FandF does not exist

umm hello we already talked about double clutching (or double declutching as they call it on that site) so yes of course we know the technique exists, we even mentioned is required on trans cases with bad or no syscros.


And the link you provided is to the heel and toe technique which to quote from that link of yours:

This technique is often confused with double declutching which is a seperate process that can be used to assist your shifting...

so why are you trying to correct us?and why the double post?

Bottom line:
double clutching isn't used in drag racing, it is a technique that aids in downshifting. You don't downshift in a drag race.

I downshift everyday, because my vr4 is prone to excessive synchro wear and I want them to last...it is a good habit to get into, however as said, it has nothing to do with drag racing.
So as Neutrino said, DON'T EVER take anything from F&F as real, and you'll be fine. General rule of thumb: Paul Walker and Vin Diesel know less about cars than you do.

early april fools joke?

Paul and Vinn would be very sad if they read this thread

[tr0ike]

what the hell IS "granny shifting" anyway

[lamehonda]

Shifting normal

clutch-change gear-release clutch

[vette_7t9]

granny shifting means shifting before engine potential i think, i saw it being mentioned in a drag racing video where the guy shifted at 4 grand.... anyways from an M5 instructional video, it says double clutching saves your transmission life but is not necessary in cars nowadays. Is heel toe a double declutch action or is it just blippin throttle with clutch disengaged, as in single clutch?

stop watching fnf it's just corrupting your mind. Nothing good comes out of that movie.
