Well, since one topic was posted on this as an invite, i'll add a second. Only a bit different.
This weekend NASA is running a track event on the East track at firebird. They have a High Performance Driving program where all you need is a helmet and a car in good working order and you can rail around a racetrack all day.
I'll be there with my 510, and invite anyone who isn't worried about oil starvation to come out and run, (this is the same track i blew my motor on...) perhaps it's more appropriate for the focus guys (who might enjoy seeing the full race prepped foci running around).
