A 2.0 on street tires is about as good as you can get.
I should be capable of a 1.8 on the tires I have, but I need to make the rear end more stiff and an LSD would help a ton. Without an LSD I should still be able to hit a 1.9 or so...thats about as good as I've seen on SRT Forums. Some of the guys with modified suspension with the stock LSD and slicks have gotten down to a high 1.6x
