Bob- I ran the outside hole a few times at SoCal. It makes the back end really lazy. Makes it easy to drive if you're having trouble with the back end being too twitchy, but I don't think it's a fix, more of a band-aid.
David- Glad you liked the car. It'll just get better.
I had a good night at SoCal. The setup Donny and I came up with using some of his experience there with the original Mission worked really well. We've got a few more things to work with but I was really happy with it.
