Try calling Tire Rack. They usually pretty sharp on this stuff. I'd probably start about where you mentioned. But really have no clue. I run more than that for autox but I'd be uncomfotable with it's autox characteristics (caused by the high pressures) on a high speed track. Just my $.02. You can give me change if you'd like.
Definetly let us know how it went. I'd love to do a track event too.
