I was told by a dealer to double clutch instad of heal and toe, i.e (and you to do this fast) push the cluch in, go to neautral. let the clutch out, blip the throttle to match speeds , push the clutch in , then change to your next gear, let the clutch out, so they tell me this also does one thing heal and toe does not , which is to match the transmisssion synchro speeds, saving on wear inside the transmission. - maybe true, maybe not.

I think that's ridiculous. That's what synchros are for and your 997 has 3 for each of the first 2 gears. That is, synchros eliminate the need for dble clutching. Try double clutching on a race track and you'll see how ridiculous it is. The only thing double clutching is good for is teaching the concept and skills for throttle blipping. Perfect throttle blipping including during heel/toe means absolutely minimal wear on clutch and tranny. Dble clutching is massive overkill.

I've got big feet, so I "toe and toe", which means toe-ing the brake with my big piggie, and toe-ing the throttle with my little piggie. My heel hangs out below, cheering the piggies on...

I presume that's when you're on your way to market.
Trouble starts when big piggy slips off brake and joins little piggy and the other three on the throttle - thats called 'Miss Piggy'.

H&T is not necessarily how most race car drivers downshift, nor the best way to downshift. if you are going from 4th to 3rd as an example after braking you put the car in neutral WITHOUT using the clutch, blip the gas, depress the clutch, select 3rd, and release the clutch. it is much easier to match revs with the trans in neural, since the pinion gear, i believe it is called, is also being spun up. if you blip the gas with the clutch in the pinion gear will need to spin up before it will engage after you release the clutch. is it modified version of a double clutch, but since you do not use the clutch to put the car in neural it takes the same time as a H&T downshift.

GA997s - Maybe the confusion is that I should have said while braking not after braking. It takes the sametime as a H&T and is easier to match revs. When is you next race?

I've been trying to practice this since I got my 997S. Without heel & toe downshifts, the journey is not as smooth! I keep practising. Hopefully, one day I will get there!
