It's common to mix up heal toe, which is really about matching revs for a downshift while braking, with double clutching, which was originally used by non syncromesh transmissions and early crashbox racing transmissions (or broken ones...). You can do either without the other, but any kind of track or high performance driving, Heal/Toe is an essential skill. With modern boxes the only real need for double clutching is if you have a syncro go midway through a race.

The brakes are used to slow the car, not the engine, if you are driving at the limit of adhesion in a corner a downshift without proper rev matching will upset the car and put you in the weeds. When you're right foot is busy on the brake you use your heal to match the revs so the car is balanced and doesn't unload in the corner and cause a spin.

It looks complicated and like you could never do it, but after a while it is second nature and I use it on the street for any kind of spirited driving. Once you get it down it's fun...

I learned it by practicing on the streets and twisty curvy roads. It becomes second nature after a while, until you are wearing a suit and dress shoes that are a little to big for the foot well and you end up over reving all the time and looking like a complete moron.

I did the same as you to start. Watched some YouTube videos and went to town.

Do you need to adjust the pedals on a 964 to optimize heal and toeing?

The reason I ask is my brake pedal has little travel....even full on brakes/pedal-to-the-floor, the pedal is still much higher than the gas pedal. I just can't see how I would extend my foot far enough down/over to even blip the gas pedal.

I did because to do it correctly, I had to brake quite hard, harder than needed under normal driving circumstances.

On a C2, I did set the brake pedal a bit lower and I moved the accelerator about 1 cm towards the seat, 1 cm towards the middle of the footwell (simply drilling extra holes in the plastic tab of the pedal that contacts the floor).

It mostly depends on your driving position.
Some find that the stock settings are fine. Some drivers use the side of their foot rather than the heel.

Just make sure that the brake pedal stays well clear off the floor...

So now we have all mastered heel and toe, the next step is to coupe it with left foot braking, see here from 2m 08s onwards:

I noticed that too and was surprised.

Having watched it a second time, I have changed my mind. It looks like he goes 100% full throttle as early as possible, then he releases throttle as required.

So I wouldn't say jabbing the throttle. I would say reducing power.

Kind of like braking. Push hard and if you lock-up (hopefully not) then release the brake. Alternatively, full throttle but if you cant handle full throttle then release.

It came together for me watching Jaque Almeras pedal his 3.0 Monte replica, with a 915 box, too.

Cover half the brake pedal with the right foot, then just rock your foot to the right. There you go, easy every time.

You do need to be making a smart pace to be -really- into it, of course due to the brake travel already mentioned.

For me, it's another part of driving the car, and I do it all the time.

Yes, that seems to be the easiest way with an un-modified Porsche 911 pedal box: use half the brake pedal and rock your foot off to the accelerator pedal.

Yes - and learn from the master.

^^^^^
Ballet...with thousands of people standing inches away!

Here's a great video of Hurley Haywood talking about heel/toe...
one good point he brings up is practicing while the ignition is off...
another good point is you only need a little blip, about 1,000 RPMs worth.
Good stuff, explained in plain and simple terms!

I like his quarter drill @ 15:25

(heel/toe comments start at 12:30 into the video)
