Got this tires on a VW Golf GTI highly modified with about 550hp. This tires are use 1/3 track 1/3 highway, 1/3 city.
They are great, much better than the previous R-S2, seems to last a bit less, but the handling diference is much better. I would think that the next level for this tire would be in the semi slick side. The price is awsome for what you get.
Maybe the problem would be the handling in cold, if this tire is cold, it would not handle as good as if it would be warm.
This tire help me improve a lot my lap times at the track, and let me break later and take the curves faster.
For a tire like this I would expect worse handling in wet than it has, I was suprised when I use it on wet, but if your are going to use it with rain or wet pavment, I will recomend you search for another tire.
I will recomend it, and buy it again...
