I don't know if you have been watching the Optima Challenge on MAV TV. It is on at 9 PM (MST - Phoenix) tonight (26 Feb) and this segment will be last year's finals at COTA. Chris Ramey has been tearing GTV up with his C-4. There are a couple of C-3s and lots of Gen I/II Camaros, mostly with LS7s and full independent suspensions. Ramey has an LS7 also, with C-4 suspension and good aero. His road course times are often FTD - even faster than the GTL and GTS cars. Usually only Austin Barnes in his twin turbo, 1000hp C6Z is faster on the road course.
