I've run against the Lotus Exige and the C5 & C6 Z06. Me on Hoosier R4S03s and the others on R6s, equal drivers. I've also run against a Superformance with a Roush 427R, and Hoosiers. The SPF wasn't close to the others... cornering or on power. The Exige was off by 8 sec/lap at Autobahn CC in Illinois, although his corner speed was right there. At Blackhack and Autobahn the C6 Z06 is the closest I've come up against... about 2-3 seconds off. The driver of the Z06 and I are within .1 seconds racing in equal Karts, so we feel it was an accurate assesment of the car's abilities. At the end of the day the Z06 drives home with the air on and my Cobra goes in the trailer... winched in at that on account of the button clutch... You are going to need a serious Cobra...
