im glad this subject was brought up, i posted in another forum/website and no response, i as well recently purchased a set of race take off(michelin power race) meduim soft compound front and rear, and was wondering who is using them on street would you recommend them and i have pilot power still new and debtaing if i should swap them and use the power race until the wear and swap back to the street tires, i have heard some people swear they would never go back to street tires also usally the edge are used up i mainly street drive and ocassional twisties, but i dont/cant go that low anyway so i doubt it matter if the edges are used up , i seen some guys ride with slick but only in the summer, sorry i am not try to hi jack this post, by the way when you by race take off make sure you know you buying from, or good feedback on ebay who sells lot of take offs will lead you in to the right direction by the way i dont know if you bid or won that tire but a ebayer who i bought from and is reliable is sbmotorsports on ebay,i was refered to buy from him,thanks
