Y'all have some deep misconceptions. Ford makes factory track cars as well, the FR500S. Ford has a pretty big roadcourse history in the Mustang. SRA's seem to work just fine on roadcourses too, it's regular crappy roads that they have problems with.

It's a silly argument to say 'average mustang owner vs average camaro owner'. They've been going back and forth against each other for a LOOOONG time.
