I actually try to use my heal. I used to just use the outside of my right foot, but I slipped off the brake one time. Luckily no one was in front of me.

It depends on the shoe, too. I have one pair of shoes that always seems perfect, and I hardly have to think about it. Other shoes it seems like I can't use my heal no matter what, so I use the outside of my foot. I bought new pedals ,too. The brake pedal it much harder to slip off of now.

 

Why on earth would you want to double clutch on a car with synchros? We're not driving cars from the 50s or big 18 wheelers here.

As far as the topic goes: I roll my foot too and my heel never touches the pedal. Just rev it high enough so that when you release the clutch the RPMs remain constant. If you release too soon or too late then you feel the jerk as the engine speeds up or slows down. Just llok at the tach when you do it and try to figure out if you need to rev more or less.

 

I agree. You can't count RPMs here. I'm still learning (teaching myself) and it's really a feel thing. It just "clicks" eventually and you know just how hard to shove the gas at the exact right time while the clutch is in and you are shifting. The rev blip happens so fast - you can let the clutch out when the revs are rising, peaking or falling, as long as you aren't too far off - you're going to hit the gas hard after you let the clutch out anyway so a little buck shouldn't hurt too much. It's so smooth when you get it right though.

 

To answer you questions in simply words:

1) A general rule of thumb is about 1,000-1,500rpm per downshift. But as you are more at ease with the moves, you can fine tune your rev-matching skills.

2) The "right feeling" of H&T is no special feeling-->that's the whole point of H&T....meaning no bogging, no jerking, just smooth engine braking and smooth slowing and smooth shifting.

 

Agree.

 

i usaully slip,feather and drop it.then give it full throttle.

 

o.O sounds an awful lot like a launch to me... heel+toe is used when entering turns to allow you to benefit from engine braking and staying in the powerband when you start to apply the gas at the apex of the turn. road racing is all about being smooth, not mashing the pedals

 

Why would the type of clutch make a difference?

if u watch the video of the Evo9 driven by the WRC driver.....he doest use heal->toe.....so why do you?

 

You can't compare the driving techniques of Gilles Panizzi, the WRC driver in question, to normal road course driving techniques as the two styles are very different.

 

It is also hard to compare different equipment.

My Formula cars and when i was running the Prototype I didn't heel and toe. Mainly, because I dont use the clutch at all.

I am betting that there is probably some differences in the gearboxes.

If you were to watch the SCCA Rally stuff and the cars that are closer to stock, I bet that they are using heel and toe, and that its helping to do the same things that it does on a roadcourse. Ease on the gearbox for longevity, consistancy in shifts so that it doesn't upset the car, and to keep the wheels from locking up on downshifts. (more of a RWD thing)

because if you break and not rev match, it shocks your t-case, not to mention the jerking forward and back.

That was the only way to downshift a long time ago, rev match, but now we do it because it just makes the transition in turn a lot smoother.

You don't have to do it, but there's the answer if you didn't know.

 

What does any of that have to do with double clutching?

 

double clutching, rev matching.

why, you don't rev match when double clutching? there's no point for double clutching if you don't rev match.

-sigh...

 

You don't know what you're talking about, do you?
