NASA Tire Rule Change
This rule affects me and a lot of the people in the TTA C5 Z06's.

I am not sure about that. I do know according to Hoosier's website the 255/35/18 has the same tread width as the 275/35/18 or maybe it's 275/40/18. The 255 on the 17 inch wheel is not like this. The guy in TTA who won Nats had a c5 Z06 and ran that tire. That gives him 10 points back to do other things. It's kind of a cheater tire. I use it, but I can just add 4 points worth of weight back to my car and run it still. The TTA guys will have to change a lot and run the 275's or just stay 255's. Either way they have to lose more points worth of other stuff to run it. The guy who won TTB at Nats ran this same tire too. His car would in TTA now because of the new rule change.
It's kind of crappy because the TTA and TTB National champ ran this tire anf their record setting times are harder to get to now because of this rule.

What does NASA say about the Goodyear DOT tire? In T3 we run a 245x18 tires and T2 runs a 285x18 tire. If it affects those sizes they will chase away SCCA guys. Maybe thats what they want.

I think the change is silly since as some have stated there are other tires which could be thought of as cheater tires (I run 225s that are pretty much 245s). But, at least the change is not meant to hinder a specific car (though some argue it affects only the ZO6 vettes), the rule applies to everyone.
How difficult would it be for a 350Z built to run NASA PTA/B/C, to enter an SCCA event and race T2/T3? Impossible unless it was built to be a T2/T3 car.
How easy is it for a T2/T3 350z to enter in a NASA PTA/PTB/PTC event and race? If you take the time to understand the NASA TT/PT classification system you would realize how flexible it is vs the SCCA T2/T3 system. For example, cars like the solstice/sti/cobalt/mustang aren't given "consessions before ever being on track," they would be classed using the points system or a combination of hp/wt ratio and points. No system is perfect, but NASA is more inviting than SCCA w/ respect to classing.
