It doesn't take any different motion or technique than your normal shifts - just a slightly quicker pace. Redridge has it right. Find someone who has good track experience and watch their hands and feet on a lap. You will learn a lot from that. You won't see jerky motions. Everything is smooth and orchestrated.
Exactly! I really should find someone who is a pro and watch him driving..
Thank you for sharing your experience on track...mathism
and
THX for all the comments fellows... They are really helpful!

Ray, that was a great clip... that driver does have a crazy technique..
How's your 996TT by the way??

I wouldn't worry about your transmissin when shifting through 1-2-3-4 quickly. Even if you don't rev match, and shift as quickly as possible, you're not going ruin your tranny. You could even skip a gear and be fine (1-2-4).

Going the other way, that's the real issue. 4-3-2-1 is MUCH harder. And skipping gears is much more difficult to get right. Going 4-2 (and still being in the peak torque band) is pretty tough. That's going from around 110-120 down to around 40. Pretty cool when it works though

Alan, I saw your car at Bridgeport 2 days ago. I might be go out and test my friend's 650hp TT this weekend. If you interest, we can meet up. I'm no where near a pro, but I believe I can show you some quick shift if you want!

Nice video clip, but a bad example for us. Those old Group B rallye drivers are flat out CRAZY. (How about the fans right on the edge of the course! No way that happens in the US.) They use the clutch for much more than shifting. His shifts are silk though. That guy is a Porsche test driver now.

you're not worried because it's not your tranny and it's not your wallet that will get it.

advising someone that skipping gears is cool is silly advice as well. don't skip gears esp on the upshifts.

After doing a lot of autocross, in tight racetrack setup. I agree about your right hand going back on the steering wheel after each shift. I have found that it is faster to return the right hand to the 5 o'clock position rather than 2 o'clock. this is a rather an unusual hand placement, 11 o'clock and 5 o'clock, but in tight autocross tracks with very quick turns it works well.
As far as grip pressure, between purple and pink.

Why not?

You're not going to kill your transmission skipping a gear going up. You will simply miss the torque band.

Clearly you don't get to the track and understand what your car can do. Don't tell me you're one of those people that takes "spirited drives" on the public roads and preaches how to drive fast...

i don't claim to be anything nor should you with your street car track as a hobby mentality who doesn't have the talent or commitment to make a living off going fast around a road course just like 99.99999999999999% of the popluation including 6speed.

skipping ears on the upshift is silly and NOT good practice.

Why not? If you have some info or data that shows why, it would help all of us understand.

Skipping on upshifting is no more dramatic on the transmission than killing the car in first gear. Nobody is saying do it every time you drive. But doing it, isn't going to kill your tranny.

We all know you aren't going to take your pimped out car to the track. Just busting your chops.
Did you get thin skin all of a sudden? I didn't take you for the sensitive type. Geesh.

And don't have to make a living at something to have some understand of it. Clearly that applies to you, as you have input on many topics on this board, but I don't recall you making a living selling/marketing/building anything Porsche (including wheels, tires, body kits, etc. etc.). Maybe you do it on the side.
