The only thing I think is HILARIOUS here is, you only pointed out the Camaro WINS and where it lost, you just left it off. I don't care because you were only trying to point out wins, but it is kinda... "forgetful" of you.
How many people road race their Mustang or Camaro? Perhaps 1/10th of 1% of owners?
Aside from that, in SCCA racing, the real truth is, the Camaro(5th gen) has had it's posterior handed to it for years on end. I'm NOT a road racing fan myself. I mean, I like to watch and all, but I'll never waste my money actually doing it again. If I do, I'll get a Miata and do it on the cheap.
By the way, by the 3rd lap, the Mustang posted a slower ET... it was still faster overall for the 1st through 3rd laps, from the looks.
More importantly perhaps... ONLY the brakes can be pointed to as to the hy GT500 lost, when it lost. If that's your ONLY problem... a quick change by any owner will alleviate the problem. That's a win all by itself.
Now, I'm not buying a GT500 because of it, but then, the facts remain. Th new GT350R, by contrast, will ANNIHILATE the GT500 on basically any course where long straights can't create a win. I won't be shocked or offended to learn the same GT350R does the same to the Z/28 and so on... it will, guaranteed. For the next Z/28, or ZL1... that may very well change. The 2015 Z/28 though, and any other GM production Camaro, stands little chance here. That's life and there's no need to be upset over it(not to you, but generally).
