Tom, I just finished running the nostalgia drags at Eagle Field, so my car still has the rallye wheels on it. I have the Dunlop star spec 2 on my autoX wheels, and they seem to work fine. I really don't have anything to compare them to, being my first set of "race" tires though. They are small at 245/45-17, but fit the car well. This should get you to the points page (if I did it right)
