Thanks for all the replies guys. Sorry to hijack the thread.

That roof rack scares me a little. I wonder if you slanted it forward if you could get any downforce.

I've got a 2.7 and would be mostly running SCCA AS. I don't necessarily want to be competitive, I just feel like with good tires I'd get a lot more out of the car. Of course being competitive does make it more fun. Looking at those tires I would consider getting some R888s. If there is rain in the forecast I could just leave the PS2s on.
