I'd like to see what those tires would do on ZL1. I wonder how many laps the brakes, cooling, and shocks would hold up though. I know it would be at least one GREAT run. It sounds like Z/28 can do this all day though. It's interesting to see the changes in difference in time and where each car has it's advantage. It reminded me of watching GT500 and ZL1 comparisons.
