Double-Clutching (Heel and Toe) in a C4

[toomuchtorque]

When I first got my vette, the first thing I tried was "double-clutching." I quickly realized, however, that my brake pedal and gas pedal are too far spread out and the gas pedal is farther in than the brake pedal. This makes it close to impossible for me to use the heel-and-toe shifting method. How do you all do it? BTW, my vette is a 95 LT1.

I use the ball of my right foot on the brake, while using the ride side of my foot to feed the throttle.

I don't think you understand. Its almost impossible for me to sustain that position for more than 30 seconds. The gas pedal is too far in compared to the brake pedal. Maybe there is a difference between our cars in pedal placement. I wouldn't be surprised if the 95 and 87 were different.

What is double clutching and why would one do it?

Actually you might find some aftermarket pedals that slip on over your stock rubber ones. I've never seen them for a vette, only my Trans Am, but it might be worthy of your time to check it out. Basically, they raise the hight of the gas pedal to meet the hight of the brake pedal... makes for really nice heel/toe.

Double clutching and heal/toe are two different things. Double clutching is as follows:
To go down a gear, put clutch in and put shifter into neutral. While in neutral let out the clutch and rev the motor then put the clutch back in and shift into the lower gear.

Hell/toe is as follows:
Put the left side of your right foot on the brake and use the right side of your foot to blip the throttle for downshifts.

I heard that in some older transmissions, that you had to double clutch?? But that in newer trans, it is not needed, just optional?

Correct-o-mundo!

In the old days, the phrase often heard was "Grind me a pound of that!" when someone clashed the gears when shifting. Double-clutching was, and still is for that matter, an art form which takes some practice.

The synchronizers are better nowadays, so the need for double-clutching is usually unnecessary. There are occasions when it still comes in handy though, and it makes for a smoother gear engagement (shift), such as when one is road racing and you want to keep the revs in the upper range.

just for converstion

The saying "grind me a pound" as i have often heard it, and "clashing gears" is actually incorect. your gears never make contact with each other. The grinding sound that you hear is actually the teeth on the collar not fully engaging in the side mount holes in your gears, (another reason for double clutching). It alows for the collar and gear to be at correct speeds befor the collar teeth with engage. Along with that, it is also not true that you can throw out your trani by shifting into reverse while go'n down the highway. Your collar teeth would never engage. But it would prolly sound terrible.

Re:

True about the Reverse ingagement, but wouldn't that turn your sincrows into dust? Also I once saw a guy that had a push button on his shifter that would turn on a lower MSD Rev Limiter (4500 or something like that) so that he could power shft smother and faster.
