i read the A048s are awesome too. alot of porsche guys run the pilot sport cups as well. RA1's and hoosier R6 always seem popular as well. some guys had success on the nitto NT01s too. sooo many choices
yeah sierra is gonna have a huge budget, they are a pro race team. i love when you see teams who really push the envelope. not many teams have enough money or the know-how to really do it.
its good for the sport. hopefully there is a rivalry with the japanese race teams and them. will be great for watching and maybe some crazy innovation.
