You have quite a bit of rubber out back and at 31" tall you might want to look into going with a 4.57 gear instead. 60 mph is only 2080 rpm so it is still going to be pretty low rpm on the freeway. If you drive in the car pool lane in LA you will only be running 3120 rpm at 90 mph. You will be aerodynamically limited before you run out of gear.
Look for the 4.57 gears vs. the 4.56's as the 4.57 has fewer teeth on both the ring gear and pinion so they are a little tougher.
