Thanks for all the replys. I'm not new to autocrossing. Just new to autocrossing a corvette. I've autocrossed Porsche 914 fours and sixes for many years. My real love is driving on road courses. I'm a Porsche club driver's ed instructor. The only corvette I've driven at a autocross is a friend's at an autocross. It was really different than my 914. He drove my 914 and was really impressed. Thanks again for all the info.
I think you'll find the new Vette to be a lot of fun. If you get the alignment set up properly it handles great. It will be a little slower to turn in than any of your 914's, but once you get used to it, you can use the power to your advantage.
Have fun!

And the steering bias can be tuned a bit through camber changes, although so much of the car's attitude is a function of right foot position that I just go for best grip.
I do find that initial understeer has a lot to do with braking technique; a nice smooth roll onto the brakes will plant the front end well and improve turn-in. Of course that's of limited use on an auto-X course where everything happens very fast!

Not the case. He's driven my car. We've looked closely at my tires and they look like they are rolling over when I drop the pressure. I am new to autox (< 1yr).

I think you'll find that the PS2s are much more responsive to pressure changes, as well as being somewhat stickier to start with. I run them at about 36 front / 33 rear for general fooling around, might go another 10% or so for an auto-X.

Like everyone else, I'd make adjustments on each run & see what effect it would have (time wise & looking at the scrub boundary). I was suprised to see how little effect pressure changes had on both my time & the pattern.
As you state, the '07 requires a smoother hand both on the brakes & throttle.
With the PS2's, when you autocross, do you go another 10% up or down from your street pressures?
