Will a SC 370Z be able to compete with a stock C6 Z06

This is not accurate. I would actually give the edge to the Z06 with a professional driver and the edge to a GTR with an amateur--Z06 is a handful.

And for what it is worth, a C6 Z06 will likely beat a 370Z SC or TT on a road course given equally talented drivers. Z06 is lighter, has superior torque curve, vastly superior brakes, better suspension geometry, way bigger tire patch, and let's not forgot--won't overheat after a few hot laps.

With all of that said, I learned a very important lesson at BMW track school when I got a ride with my instructor for a session with the top class people. The instructor had a 330i (sedan) with ONLY suspension and tires, and he was able to chase down and pass a 700 AWHP 911 (996) with full race suspension, tires, brakes, etc. Why? Because he was a vastly superior driver. It's a foolish man who thinks WHP and TQ are going to dictate which car will win at a track, other than maybe a drag-strip. If you want to go faster around a track, forget WHP and learn to drive a slow car fast, then translate that to a fast car.
