I had the Pro System Plus installed at Arrington's on my SRT8. Dropped the front about 1.5" and the rear about .75". Has a nice rake to it. Handling difference is night and day, I think it actually rides better than the stock suspension. I'm glad I didn't have the Sport System installed because the front will probably be low enough where you'll have to sweat the spoiler clearance everywhere you go. I had a Vette like that and it was a pain. I would definitely go with the Plus system though.
