Actually, yes my car has passed 360s and NSXs on the street (obviously) and at HPDE events. My muscle car is generating almost 600 hp and in excess of 620 lb ft of torque, so these cars don't have a chance on the straightaways. Yes, these cars can corner better than my 55, but the AMG actually corners fairly well considering the lighter wider wheels, MPS2, light weight rotors and HP pads I have installed. I have reduced almost 80 pounds in unspring weight which is substantial and has improved acceleration and handling.
At HPDEs I am able to pass these cars on the straights (especially at faster tracks with longer straights or bankings) when signaled, but need to slow down more in the corners, but they are not allowed to pass in the corners and once the straights (only designated passing zones) come up, I am gone again into the horizon. Of course as a courtesy, I let them pass me as well on the straights, so I don't hold them up in the corners. BTW, I don't remember getting lapped during these short 20 minute sessions. If these were race events with passing allowed anywhere, then the outcome would be different, but they are not.
I know my car is not a track car by any means, but it is formidable nonetheless considering its a 4100 pound luxurious muscle car, especially on the straight sections.
BTW, the reason for the Z06 or whatever is to have a dedicated track car versus using the sedan. BTW, I have learned driving school 101 many years ago in my previous E36 M3, so I am not a rookie to HPDE events. (Said with a straight face)
