Ive been doing some reading and I think the 520s a great choice. I have the KDWs right now as well and love em. I do not want to go down in performance at all. I think I will do 17" wheels real soon and go with the P-7000 its supposed to be sticky as hell, pure summer tire though. If you get the 520s or the RE post a comparo as to what they are like compared to the KDW. Thanks
