I've lived with two Vettes in autocrossing and track, and run Z06s (C5 and C6) at Spring Mountain. I've run the Kirkham with all manner of other cars (and most other Cobra makes), and I really think the best mfg to start with for a dedicated track Cobra (within reason) is JBL. I could not hold the line John was taking during two events at Fernley (I'm not a bad driver, and John ain't as good as he thinks he is
)...though the straights started balancing things out.
...and let's be honest, most folks aren't hitting 150mph for any period of time at club events, etc., so the dreaded high speed concerns in a Cobra simply don't coming into play all that often. Even at Willow Springs, still known as the fastest West Coast road racing course, you've only got two places where you might get a bit nervous (depending on the cross winds). On a tight track, Vettes start getting real damn big...even the physically smaller C6.
I don't know how many times I've watched Archer and Smith reel in GT40s at the Historics. Our Cobras are a damn sight closer in performance to original Cobras (hell...exceeding them in most instances) than Z06s, etc. are to full-on endurance racers. Cobras do have one great advantage...outward visibility. When you're actually driving in some traffic in curves, it becomes as important as anything else.
A damn good driver and a moderately tight track...a well-turned out Cobra will do just fine.
