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
