The Time Attack entrants will be running concurrent with NASA's Time Trial group. I'm not sure yet how that'll work out for timing and scoring, yet.

The Time Attack classing and rules should be available in a link above. NASA's time trial rules can be found by going to www.nasaproracing.com and following the links.

I stated it previously, but NASA's Time Trials are essentially a race group with open passing. By open passing, I mean that other driver's may or may not give you a point-by and a faster car can and will pass slower cars anywhere on track. In March at Road Atlanta we had about 35 cars on track at once.
