Living with 3.91's

The 3.91's are perfect for the 27" Dunlops I have right now - for 1/4 mile, that is. I would not recommend them for ANYTHING else. It's taching around 3500 rpm's at 65 on the highway. The 3.23's I started out with after I first installed the new rear however, seemed too tall for even normal driving. Cruising the highway was good, but seemed to take too much clutch to start out and slower pulling up through the gears.

So 3.55's probably the best compromise. But still a compromise.
