Personally I'm running high red group times and I'm running DCIII's good grip and perdictable. Although I am going back to "Race Tires" because I'm a hard on the throttle person and I have already gotten the DCIII's slipping at jennings (and i got warmers cheap)...plus the ape has a lot of torque....ride what tire you like till it's moving a lot on you then try something different.
