GT3 Track alignment
 

I have a 2007 GT3 with Michelin Pilot Sports(not the Cups), and it seems much more prone tothe back end breaking losethan any other Porsche I have owned(including a 1986 Turbo). I've heard that the 996 GT3s needed to have a track alignment tomake themmore stable, and I was wondering if that would help my 997 GT3. Also, will the Cup tires make that much of a difference? Basically - can I adjust the car to make it more stable, or is it just that much moredifficult to drivethan any other Porsche?
