The interesting thing I was told by a top notch instructor and accomplished racer is that R Comps have more grip. But drive it as fast as you did on street tires, just figure out those couple of places where you need to use that extra grip. Don't tear around the track because you'll wear them out really quick...which was what I was doing.
