I used two sets of these for Track Cross days at Summit Point on two very different cars. These Kumho V730's are fantastic. I put a set of 205/55-16 on a Mercedes 91 300TE 4matic a while back and it had more grip than power. Great on the track. Very composed on this AWD wagon. I then put a set 235/45-17 on a 2006 Saab 9-3 Aero and took it to a track weekend. These tires really worked great. It was cold in the morning (35-40 degrees) and the tires took a while to heat up. They were squirmy when cold, with the tail coming around on aggressive corners. Easy to control and no bad habits. They broke away predictably. They don't like being cold. They were much better in the afternoon on the first day with temps in the 50's. On the second day, temps were in the mid 60's and these things stuck like glue. I think they are pretty tough and have even wear and will last quite a few sessions at the track. I drive about 100 miles to the track and they are fine on the street as well. Good ride and not loud. Overall, a fantastic 200TW tire at a good price.

This tire is absolutely amazing, I have these on my 97 Miata and the grip is unbelievable. Even it being a 200tw tire they are still lasting quite a while even with 4000 miles of hard driving on them.
