For endurance racing, I really like the Cobalt CRB XR3, they are great pads with outstanding wear. I am getting 8 hours life in a Integra Type R. PS, they are also easier on the rotors than the hawk blues (which were our old goldstandard till we tried the cobalts.

Also, I like the BFG R1 tires. I think they are comparable to the hoosiers, but give twice the life. They are good tires. If your budget is important, sometimes you have to spend money to save money. There are both worth it.
