Thanks for the tips. I've done a few autocrosses this year and would like to get a lot more serious about it next year. Getting more serious of course means getting some better rubber. That's one downside with the Cayman. There's no way to transport your race rims without another vehicle. Are there any good tires that I could drive to an event?

I'm curious, but wouldn't your exhaust take you out of the stock class since you removed most of the cat?
