There is an article at Michelins website that disucsses the GTS Le Mans battle between the Ferrari and Corvette and how racing tires played a big role, especially in 2003. I found it rather interesting.
The Ferrari / Corvette battle is one that has been raging over the last few years with the GTS cars. It's always a great match. As much as I love ferrari, I'll always be cheering for the Corvette when they are racing together.
