After the first trackay, I felt I did not want to destroy my expensive and awsome Continental Sportcontact 6.
So after 6 months and 4000km with the car, I bought the 4th set of complete wheels for my wife's luck

I'm testing a featured Federal 595 RS-3, these will only be used for trackdays.
Therefore, I think they are good and do not go on even more expensive tires now ..
Will try these before winter, because soon the winter tires will be on ...
Much tire change in the future ..
