The main thing I use the car for is to drive to school and occasional driving around town, so like I said before I don't ever really drive on the highway, and the highways here are max 65 MPH anyways, so the speed limits are a bit lower anyways, I would spend most of my time at 45-50 MPH max anyways.
So I guess the 3.91s would be the best choice for what I want (acceleration over speed) If anything I can add a bit more tire on the rear, which I may do anyways because the new rear end can accommodate a bigger tire. Because currently the car isnt the funnest to drive, the 2.76s suck the life outa it with my engine combo, just dont want the 3.55s to only be a marginal increase in performance.
