Well, the tires are not totally new - I bought the car in April 2006 and have put about 8000 miles on them. I did one Autocross with Sammy last year and you are absolutely right, I made a TON of mistakes, but had fun none the less. I hope to get a couple more under my belt this year, and I agree that if I start doing this often a second set of wheels / tires would be a sound investment...
BTW - your PM inbox is full
Thanks,
Nick
