Default 3.90's anyone??

I currently have a jlt intake, o/r x pipe, pypes mid muffler system, and 285/40/18 street tires. I consistently run 13.1 @106. Im looking into the motive 3.90's. Does anyone have any experience with these, or know anything about them? Also would they bring me in the 12's?

Yes, they are horrible. Motives suck. A lot of places won't even install them. Do you have a tune? If not, get one. Do 4.10s if you want gears ...
