utkinpol, 335's in the rear with 245's up front is not a good combo. You don't need that much rear tire on a 997S, especially with 245 or even 255's up front.
Anyway, some of the things I been taugh lately, read about and practice are:
Over slowing a 911 on corner entry especially in faster type of corners is something that is a comon mistake especially in the DE crowd. I was taugh slow in fast out. While that is safe for total beginners it is not the fast way. I've also seriously adjusted my driving line from very late turn in and apex's to something that is more of an arc.
I've learned that since the weight is in the rear of my 997S that I can take corners at a higher speed than I thought. This is because the front tires are not being over loaded on my 997. I've been taught that I can get off the brakes eariler and let the car sail through these type of corners because now my car has more of a neutral weight distribution. On some of these corners I can use some throttle maintanance after turn in and because my car is more balance I can get on the throttle earlier.
I've also found that if I am understeering in a corner I can acellerate just a little later and smoother next time through this particular corner. There is no need to add more steering and keep on understeering through the corner.
Also I use to think and was taugh early in my driving that I should either be on the throttle or on the brake. This is really not the correct way. Because of this I was having some mid corner push. As my corner speeds picked up I learned to be a little more patient.
All in all I practice these things but after some practice I just go out and try not to OVER THINK every thing and I just drive the car. That seems to work best for me...be aware of these techniques, work on them but really just go drive the car.

what you say makes sense theoretically but practically I tried 235/295, 245/295, 245/305 and 265/335. last one was best grip and most stable setup by far.
i did not try 255/315 which probably should be a best fit to 9"/12" rims. but they exist in r888 only and most people I know personally hate them. v710 do not have 255 nor 265. and I do not want to buy hoosiers. so it limits my choices quite dramatically, practically leaving only r888 as a single choice in this sizing. i know you recommend RA1 in 245/305 for 9/12 rims but 305 is not a best fit for 12".
so, i have now 335 and 245 RA1s in storage, as well as 255 r888, so during this season I will have a chance to run those too, with 315 r888 when i`ll find them half priced somewhere.
for AX i think i may try 275/335 if I`ll make 9.5" or 10" rim fit in front. will see. it is all fun anyway.
from what I was told and saw myself cup cars in the shop I use get 10" with 265mm slicks in front and 12" rear rims with 320mm slicks. just something to take to consideration, I would say. but they have more camber, way stiffer springs and sit much much lower. still, there is definitely some R&D behind what people with big $ do, I think.

Another corner in which to practice this may be T6 (the Laces) at Watkins Glen. Many folks tend to enter from all the way track right, brake hard, turn in & apex late, and square it off. Whereas coming in a bit off the right side (which is where the car naturally winds up coming out of 5 most of the time anyway), braking a bit sooner & lighter, then turning in a bit sooner & with less steering angle, and thus "hugging" the inner curbing for a bit longer, often results in more midcorner speed & exit speed down to the Toe.....as well as a more stable car.

You summarized them nicely, and to me proved my point of getting coaching. when back in the day we would have another PCA instructor ride with us, they thought all was great. then have a race coach ride with you and your learning starts anew!
see ya at 48hour
