Wait, I don't get it when u say inside and outside the track. Please clarify.

Yeah, I'm looking for performance data, like the info you see in car magazines. The ChronoGPS that BEJAY1 posted is pretty close to what I need (acceleration and braking), I want to add lateral G's, if that can be computed w/gps data.

My datalogging can show me the path I'm taking, and I overlay w/Google Earth. That's no problem.
