I drove with the ES100s on the street for a while then switched the wheels to my auto-x wheels... the tires are very disappointing for the price. They are good in many areas, but they just don't shine in any one. As for them being good auto-x tires... they do not wear very well in high lateral loading and tend to chunk and feather quite badly. The Kumho 712s I ran in auto-x before didn't wear nearly as bad and offered just as much grip at the track.
