I love the Kuhmo XS also. Raced the tire the last 2 seasons with an integra gsr and a miata. Kuhmo's as well as all 200 treadwear tires are very expensive for the xfire and hard to find this time of year for the tire sizes. Probably going to go with a little harder compound tire that will wear better and get the camber set as far as it will go to try and limit the understeer. I don't think there is a tire out there that can make a non SRT competitive in F Street. The limitations of the car will just make me work more on driving skills until I move on to the next car.
