Not really. With the power they produce, your 275 wouldn't really hold either car back enough to affect the race. Pure driver fail on the first race, typical result for the 2nd and 3rd.
I have a friend that has a 2010 SS and its crap next to the 02 F-bodies. Rides rougher, seats aren't as comfy, granted they have more HP, but they are heavier, less aerodynamic, and stock to stock, auto to auto, the 2010 lost 3 times to another friends 02 Z28 with 115k. They look good, not worth the 40k +/- IMO
