YACT: Heel and toe downshifts while braking

heel and toe is a advanced technique of double clutching. I'm sure someone mentioned that earlier. It's fun to do, easier on some cars than others due to the positioning of the pedals and how responsive the engine is to acceleration/blipping the throttle. And I'm sure you know that the toe goes on the break and the heel goes on the gas right.......

heel-toe has nothing whatsoever to do with double clutching.

nothing.

none. not related in any way.

my feet are two big to heel toe. i brake/shift, then coming out of the turn rev match and accelerate. i dont usually downshift before i brake, id rather wear out my brakes than my clutch

There's not really enough space around my pedals for it, so I just downshift and rev-match (sometimes poorly) seperately.

I would say the difference off track is so small it wouldnt even matter imo.

I wouldn't call it "heel and toe", more like rev matching.

Yes automatics have clutches too.
But since they are operated by the computer, you don't need to heel and toe.

automatics don't have clutches. they have torque convertors. The SMG and DSG systems are not automatics.

lol we can go in circles for days.

no i dont heel-and-toe because i dont want to twist my leg pressing the brake and tapping the accelerator at the same time simply to go one gear down either

its not necessarly to make you "faster" ,although it can, its to make things smoother. Thus why you do it on the track as when your going hard into a corner under braking the last thing you want to do is drop down a gear and be lurched backward as the engine comes up to speed. Thus you rev match to reduce this lag. This lag can cause you to lose traction and go off the track, obviously not a good thing unless you feel the need to drift.

now in ordinary driving its kind of what you feel like. In reality rev matching does reduce the stresses applied to your drivetrain. This is particuarly noticed in the clutch, however in the long run if you dont beat the car it should help the transmission internals as well. Its a good idea if you do rev match and downshift. Most people just don't downshift due to having to think about rev matching(atleast at first, until it becomes secound nature), however I think its a good idea and if your willing then do it.


on the subject of F1 transmissions and racing autos. Obviously you don't pay attention to them as they all blip the throttle when downshifting. This is to reduce the so called lag as mentioned before. Even some more advanced SMG and DSG transmissions on commercial autos will blip the throttle.

'bout time someone posted that.
Actual, genuine, heel & toeing is really difficult to practise. Using the ball of your foot but rocking from side to side to control the pedals is far easier and more controllable.

As for rev-matching; once you've got it right, it'll barely feel like a gearchange. It's not about holding the gas at a certain point, it's about knowing how the engine will respond to you pressing the pedal, and therefore you can just blip it quickly to bring it up to the correct speed. Looking at a tacho won't help.

I'm currently driving an automatic

Wrong. Heel-and-toe is 100% necessary in order to double-clutch while braking. Yes, you can heel-and-toe without double-clutching, but it is definitely related and is a necessary skill for double-clutching.
