You're assuming a lot of things about the buying public. The public doesn't care about unsprung weight, they don't care about total weight (except in the context of fuel economy). Most SS buyers won't ever drive their cars anywhere close to the point where unsprung weight matters at all. They want big shiny wheels and an aggressive looking car with a big engine that they can brag about. If you're actually concerned about performance, you aren't going to buy one for those same reasons.
