'Heeling & toeing' is a technique used to match engine speed to wheel speed when changing gear - more commonly when 'down-shifting'.

It is so-called because you use your heel (or, more accurately, the outside edge of your right foot) on the accelerator & your toe (or 'ball' of the right foot) on the brake pedal.

For instance, when approaching a corner, you would begin braking, dip the clutch, slip the gearlever into neutral & blip the throttle with the outside edge of your right foot (whilst still braking), move the gearlever into the lower gear & raise the clutch, release the brake & accelerate away.

Difficult to explain but this might give you the idea...

This has much to do with the reason my break pedal rubber now sits at a strange angle to the throttle pedal. :?

driving books ?

Hi Keith,

"Vic Elford states in his book on the subject"

Have you any other info on this book? Sterling Moss mentioned a book about the craft of fast driving and I've been looking for something on the subject. Ideally i'd like to get the seat/pedal/wheel angles right since they used to spend ages adjusting everything.. I just jump in and go so I must be missing something. There must be a vast amount of knowledge we could learn from, about weight and balance etc.

regards

mike

OK Mike,

The one that hot 66 links to is the Elford book. Brilliant read. Mixes driving technique with anecdotes from his racing career. Very readable and not heavy technically. Some of those books on technique get really heavy man!!! Other race driver author's books on technique in order of technical depth starting with the easiest.

Paul Frere another Porsche racer just a bit more technical than Elford. Still v. readable.

Next Pierro Taruffi. The first ever written on the subject, apparently used by the late great J. Clark. Highly detailed, so much that I'm starting to fall asleep now. It is good though so always go back to it when I wake up again!

Next up one by Bob Bondurant, so heavy I'm right in the land of zog before Bondurant has finished his analysis of the first corner at Thunderbuggins County raceway. I never did pick that 'un up again. Maybe one day!!!

John,

This is a bit of random double de clutch discussion, a few misdirections but it gets the point across eventually! :)

Highly recommended for 2nd to 3rd and back on a 915 box, these seem to be the most vunerable synchros, maybe because it's the most used change. A neat double de clutch smooths things out lovely.
