With the exception of the 3-4 Evolution schools I've taken, I've only raced my car at an autocross. Since my car is down, I have been given the opportunity to co-drive a 400rwhp C5 with an automatic tranny. The car has received FTD at the first three events of the season. The guy who typically got FTD last year has been without his Z06, and when he drove this car he had difficulty getting used to the automatic tranny. I think he's got 315 V710's on all corners, and something like -2.5 camber. Recent changes made at the suggestion of Danny Popp.

This event will sorta be a mini-road race. When we run the course as an increasing radius sweeper, stock Z06's reached about 115mph on the back stretch. We'll be going the opposite way this event, however.

So, anything in particular I should know if I take him up on his offer? Let the car shift itself? How do I prevent it from shifting in the middle of a corner? What else?

I had a few problems (IMG:http://www.frrax.com/rrforum/style_emoticons/default/laugh.gif)

On the first run, I moved the shifter into second gear at the start line. It bogs off the line and I keep it there the entire run. I thought this would limit the tranny to not go into a higher gear than 2nd, but still downshift to first gear. Wrong. Noted. I see Jeff posted that earlier. I should've paid attention (IMG:http://www.frrax.com/rrforum/style_emoticons/default/rolleyes.gif)

On the second run, started in first gear, and shortly thereafter it felt like the throttle pedal had been cut. I glanced at the dash and noticed something about active handling on the display. Turned it off. Noted.

On the third run, I turned off the active handling while staging. Same problem as second run. Since the staging line was moving slow, I sometimes turned off the motor. I forgot to disable active handling right before my timed run. Damn it.

On the fourth run, I hit a slalom cone, but I would've been about a second faster otherwise.

I couldn't get used to nudging the shifter into second, then waiting what seemed like an eternity for the PCM to decide to shift on some random whim. I didn't want it to have a high shift pressure, but just wanted it to shift when I desired it to do so.

The owner had FTD, and I was 3 seconds behind him. So long story short, I was missing the 6-speed today.
