Actually it is one of the best idea's. There have been a ton of people with vibration issues when going to a 4.10 or higher without the aluminum DS. I would never go to that gear without a good DS in place.
I would go with a Hellion Turbo system for your setup. Going to make more then enough power and still be plenty of fun of the street. If you are set on a supercharger, look at the Procharger P1SC
