I am also sure that I saw someone here has put 285/35's on stock 19 inch wheels. The tire shop didnt enjoy it but they got them on and he was happy. I am debating the 275 vs 285 for when I need to replace mine.

What was your 60' times? I always turn my TC off but I will give it a shot with it on to see how it goes. I forgot to turn it off once to do a little burnout in the waterbox (can not drive around it) and the car cut out big time when the traction control kicked in so I figured it would do that if I launched with it on.
