I happened to be in one of the few Callaway Corvette Dealerships last week while traveling through Nebraska. While I was drooling over the polished supercharger the owner of the dealerships son ( a very nice and polite salesmen) told me Callaway would be offering Camaro upgrade packages. And the they would NOT interfer with factory warrenty. I will be looking had for a 5th gen with Callaway across the back. If anyone else can confirm of dispute what I was told please let me know.
