Hmm...I agree with alot of the info here. Enigma has had very good points, so I side with him here. Tires make an outstanding difference, at all times. Wet, dry, snow, sand, you name it.
Conclusion is...CSL with the Pilot Sport Cups is a great combo and a great car. And isn't cheating as they are street legal tires. But a C6 Z06 with the same tire setup, will obliterate most cars in the world around the Nordschliefe.
