NASA Time Trial Rules
IMO the 370z gets hosed in tt classification. I can't see how the base 370z is faster than the Nismo 350z yet it gets 7 more points. There is no way to get it competitive in TTB with the added points and it is too slow for TT3. IMO the base Z should be TTC** and the sport Z should be TTB and the Nismo should be TTB*.
