Touring has ran spec for a while, but they run rubber, not foam. And TC about died when it first switched because no one thought to limit the amount of sets to use at an event. And TC is still no where near what it was in turn outs back in its day, when just about everyone was running foam. The first national in TC after they went to the spec tire, to be fast, you ran a new set every time you put the car on the track. If 1/12th is to follow TC, learn from their mistake and limit sets. I personally know, the spec stripes are faster when you "1 run" them.
As for me "quitting" after 30 years, no I won't quit, I will just run a different class and shelf the 12th scale.
And as for the IIC never hitting 50 in 1/12th, well, it never will if it goes spec. But that is my opinion, and I have been wrong before. My observations have been since the new carpet, 1/12th has seen a little resurgence and we do not need to start changing it just because some feel they are being beat by "special" tires and not flat out talent.
