proof me wrong show me someone lock up the rear and blow up their valve and burn their clutch from not heel toeing and still drive fast. (without miss shifting, or jam their gear from down from 4-2 or 3-1)


cornering angle (fix under or over steering)

i would like to see a F1 heel toe, because F1 or those super cars don't use foot clutch. so why would you heel toe??????

and i missed read the 3rd one, it's my fault..i was trying to said, if you heel toe that wouldn't happen....

you are comparing different kind of brake concepts and use.. we're are talking about driving that actually involves the use of heel toe.. i don't see why driving in circles would need heel toe...

GTR's drive themselves. Seriously, anyone with a little track driving experience can go fast in a GTR. I see it all the time

Prove you wrong? I can't prove anything, it's an internet forum. I'm just speaking from experience and knowledge.

I have no idea why you brought up F1 cars, they have pneumatics for the clutch & gearshifting and the ECU automatically blips the throttle on downshifts. They heel-toe electronically

To the OP, you might get a copy of "Going Faster! The Skip Barber Racing School". It's about $15 used on Amazon. It's not a Bible, but at least they are credible. Some info here does not meet that criteria.

The Skippy book is great, especially for a beginner. However, I disagree with the chapter on Shifting in that book. Skip used to teach double-clutch downshifting at their schools, which is what the book teaches. That technique is more complicated than regular heel-toe downshifting, and it's unnecessary. The instructors realized that they were wasting time with confused students, and recently they decided to only teach regular heel-toe ("single-clutch") downshifting.

- So keep that in mind when reading that book. Otherwise it's all pretty solid info.

Whether or not the rears would lock depends on a lot of things (that's why I said they might lock in my original post), but I guarantee you that if you're braking at the limit of all 4 tires and you suddenly let the clutch out in a low gear at low rpms, the rears WILL lock, ABS or no ABS.

I think it's obvious Heel toe is not that crazy of a deal, in japan, even first time driver little kid can perform heel toe...he just made it sound to be some crazy stuff that does so much.

I've been racing since I was 14. I've been getting paid to do it since I was 19

This is a great clip of Boris Said going around Sears Point. The three camera shot shows the feet, the windscreen view and the car on the track so you can understand how it all comes together.

I didn't look for a clip that shows what happens when you don't heel & toe, but I'm pretty sure a search of "Infineon" and "Jimmy Spencer" or "Sterling Marlin" will find one.

As axoid said way back on page one, though, it's not a technique you'll use much in autocross.

LOL. Good post.
