Wow so Team C and Reds will rule spec... What a bold statement, thank you for clarifying your intent.
I'm pretty sure if you went to some of the tire companies they would get something special for a spec tire. Then you throw Serpent and Novarossi under the bus. Are you that mad that one of the big three in on road racing is winning at on road racing? You know how Serpent gets on top? XRay? Mugen? They support their drivers and build a even stronger customer base. They listen to all feedback and make the right changes. They also have the backing by the top drivers in the country that work hand in hand with the best engineers. Serpent has rightfully earned its place on top of GT powered by Novarossi. Like mentioned above if you have a problem with that you have every chance to create your own products and drive against the best.
Don't bs us look under your name at the list of sponsors, ta da! There's your spec class. Bold move gents I'm not impressed.
