Luke, is the R6 a drag slick or road course slick? Are these all DOT? Which will yield the best times and durability on the road course race track? I have heard the non-DOT Hoosiers are more durable and yield better times than the DOT, is that so? I was following the link in the stickie thread, and it doesn't look like it identifies VCA members. How does that benefit VCA? Thx. Jim

What is the Viper Racing League Hoosier? Is that the same as the R6?
