Interesting, but like others have said to each their own.
Weird why you'd trade in a newer Vette for a Mustang, unless it was a financial thing. The Vette (as I'm sure you know) can be made to be a pretty stout and rad drag car easily too.
As for the Brembo's, I'd take that bet and raise you a few.
Bigger rotors, bigger pads, more contact patch with more even pressure from more pistons on a car that weighs the same and has better/stickier tires. Don't know how one could possibly bet against better (and shorter) braking distances? And from what I've read so far, the feel alone is much better with the Brembos too, and as you mentioned less fade (which is important for those of us who live in areas that get over 100 degrees, love to drive canyons that can include some steep downhill grades that can overheat brakes). To some that is very important as well (though less so for me as I'm not overly picky about feel unless the base brakes are grabby or completely non-progressive.
Had absolutly nothing to do with financing. Im just not a vette guy. Had it for one year and put a whole 1600 miles on it. I didnt really enjoy the car.
Assuming the stock brakes are strong enough to lock up all 4 tires, how are bigger brakes going to do any better? The abs is going to pulse the brakes anyway. The only advantage is fade, which I dont care about at all. I think the brembos are just a marketing gimick, they arenet even top of the line brembos anyway. As for the CS/GT it was just on the lot with the other options I wanted so I bought it. I could really care less about a reg GT or a CS/GT honestly. I will end up making the car into what I want in the long run anyway, and thats probably a high 9/low 10 sec street car.
