I'm only a size8, never had any problems?

So Nick do you heel and toe now? LOL
Nine pages of amusement...
It's good the F4R has no flywheel at all... so we NEED to match the revs innit?
Just like a proper racecar.
LOL! I tried some "practice, practice, practice" when I was out in the car yesterday but kept slipping off the brake pedal which gives me the fear tbh!
I think the problem is I keep practicing under light braking and it is obviously easier under heavy braking. Trouble is most of my driving is through towns and on motorways so I'll need to start driving everywhere at track speeds to get any good! I used to have a classic mini and could heel-toe under light and heavy breaking which is why I am bugged by the whole thing!
Those who can't, teach?
aren't you a teacher????
What are you qualifications Bradley? Racing instructor? Advanced driving instructor? Gran Turismo maestro?Mini was non-servo?

Isn't his name Robert?
Or Jenson?
You complete contradict yourself. He IS worried about smoothness...not weight transition in this case but the smoothness of engaging the dogs. Also this Jean chap seems pretty handy behind the wheel, so perhaps he is capable of deciding that he wants to upset the car with the handbrake (acting on the rear wheels) but would like to heel toe to stop the front wheels decelerating even more.
I'm going to try and summarise the info. in this thread so it's actually useful...
BENEFITS
Mechanical Sympathy
- It avoids using the clutch as another braking surface which will obviously wear it prematurely.
- Avoids unnecessary stress and strain on gear box internals as the speeds of input and output are matched before re-engaging the clutch rather than being forced to match.
- It allows you to rev match for non-syncro (dog) boxes which as you've stated helps engage the gears and reduces wear. This is equally applicable to a syncro box as you're not working the syncros so hard. It easier for them to match a difference of 100rpm rather than 2500rpm.
Balance & Smoothness
- Prevents extra weight transfer unsettling the balance of the car when re-engaging the clutch. Important when braking hard into a corner. If you're on track you'll often be braking on the threshold of grip/slip and a non-matched shift might be enough to lock the wheels.
- Also of benefit to passengers, a seamless shift is much more comfortable as your head isn't thrown forward as if someone just pressed the brakes even harder. One of the main reasons to use it on road as well as track!
- Prevents locking the rear wheels in a rear wheel drive car.
Skill
- It's fun to learn new skills and put them into practice. Be that heel & toe, left foot braking or taking an advanced driving course.
THE TECHNIQUE
Pivot w/heel: http://www.youtube.com/watch?v=IuoZeuSgEj4
Pivot w/side: http://www.youtube.com/watch?v=qdWSyrqEnE4
The videos above show the two main techniques. You can pivot on the ball of your foot and use the side of your heel or you can 'roll' the side of your foot across. Although the name suggests toe I would avoid trying to use your big toe for braking. The most important part of the maneuver is the braking. Safety first and all that. So I would use the ball of your foot under your big toe.
The Clio is one of the best cars to heel and toe in that I have driven. If you're having trouble doing it then it's likely to be down to inexperience rather than the type of shoes or the size of your feet.
Some cars will not allow you to heel and toe and they cut the throttle when you brake...modern VW's for example. Useless.
I would say that when driving the thinner the shoe the better, skate shoes have thick soles and give you no feel what so ever. If you heel toe properly you don't need the extra width of a special pedal or a big pair of shoes.
Would it be a good idea to create some threads that have factual information on advanced road and race craft driving techniques so people can fully understand the benefits of these techniques? If that is the case we can gather together all the info, filter out the rubbish and create an FAQ that is factual and informative?
An understanding of what goes on inside and engine and gear box will be of great help to full understanding the technique.

Grat right up and a very good idea for the club imo. A section like that would benefit me so much as I woundn't have to nag anyone with questions.

Simon de Banke - world record holder for driving sideways (I believe it was 2 hours 11mins or so when he ran out of fuel) and general top bloke
lol, what relivance is that nice car though
Nick, what technique are you using ? Lift the heel, or roll the foot.
I can see that you might have a problem under light braking with your foot slipping or modulating the brake if you lift the heel, twist and work the throttle with your heel. However, if you roll your foot and work the throttle with the outside of your foot I really don't see the need to start modifying the pedal box as has been suggested.
Are you a stunt driver?Left hand drive?
Mini was non-servo?
The mini was an X-reg Rover mini with servo assist. Forgive me, but how would this make a difference?
Brad are you Robert Barrington and was that you in that youtube clip posted previously or is that a myth?
He's incapable of a straight answer sadly. He seems to deliberately type like a dyslexic yoda in order to bewilder.

This gets better and better. So now the 172 has inadequate brakes. Odd that when tested the stopping distance was shorter than a f360 and the 911 of the day.
Are you a taxi driver?
The williams never stoped better than the 172
The 172 out brakes and carries more g's throught the corners

Because on non-servo brakes, you dont get the problem of over pushing the brakes when heel toeing. Obviously because the pressure you need is much greater so you have a finer control over them. Which is one reason race cars run them.
When youve driven a non-servo car for a while you realise how stupidly over sensitive the standard clio brakes are. People mistake the 172 brakes for being 'better' than the williams brake, however, the difference comes down to the 172 having more servo. Modern cars feel like they have better brakes because they have more servo assist.
I cant comment on a 182 as i wouldnt be seen dead in one so wont drive one, but i assume they are the same as the 172.
A very interesting read i race a spaceframe stiletto with a dogbox and sprint a 172 Cup find i need to Heel & Toe in both for good lap times!!
Just as a williams will stop faster than a 172 as it weighs less but has similar levels of grip. Its just simple physics.
