Ummm if you look up user reviews, Kumhos have REALLY high ratings. They are better than Nittos. Check out http://www.tirerack.com for some reviews. A lot of people on this board use them including myself, and love them. They are just as good as Dunlop SP8000's which I used to have (but Kumhos also last longer). Just because they are made in Korea doesn't mean they suck. And Toyo is a very good racing tire too - The Toyo TS/1 is used by a lot of guys from socal dsm and they all love it because it's a very aggressive street tire.
