Nice video of heal toe

He keeps rowing down the gears. Brake, clutch in, select the right gear for the speed you'll be driving through the corner at, blip the throttle to match the engine to gearbox speed, clutch out and smootly move your foot from the brake to the accelerator. That's all there is to it.

Changing into each gear whilst under braking doesn't really give you anything (admittedly a little bit of engine braking - possibly) and if you focus your attention more on actually driving you'll get more gain...

I use heel and toe all the time, both on track and on enthusiastic drives.

It is an essential technique to keeping a nice balanced car and keeping the rear wheels from locking when it takes up the strain of the drive-train.

It also allows you to use engine braking in all gears as you down change.

 

Totally agree that double clutching is useless on modern cars. They use to use it on very old things that required one press of the clutch to come out of a gear, then another press of the clutch to engage another gear.

This is a nice video of a 996 around Fuji Speedway.

 

Notice how he also trail brakes into the corner.

 

I was shown this a couple of weeks ago by a pro driver and it goes against what I've been told in the past - i.e. finish braking before turning in. Works well though, really does "pivot" the car around into the bend.

yes it is true a lot of racing schools tend not to teach trail braking due to the way that a lot of people just end up going into a spin.... pick any single-seater race lessons however....and they should teach you this.

 

To be better than the rest trail braking is a must. It is one area where you can gain extra 10th's on a lap time and during a race.

You know you are getting it right when you feel the back end just on the limit of slipping..... you find the car is turning the corner by itself and you can then be on the power to continue this through until the corner exit.

It is a very common technique in single-seater racing.... it does three things... (1) allows the front wheels to do less 'work' in steering, and (2) keeps temperature up in the tyres, (3) allows faster corner entry speed.

 

You can sort of compare it slightly to the way a rally car goes around a corner... they carry extra speed through a corner due to the slide and using the traction of the driven wheels to pull/push them around in combination with the tyre grip.

 

 

For trackday fun ......then better to be on the safe side rather then over the track wall upside down.

As soon as the new suspension is on I'll be heading out to Fuji to work on this. It's a nice big track with lots of run off so I should be safe when I enviably f9ck up :D

 

The technique works really well on the GT-R too which is a nightmare for understeer.
