.64 OD and 3.73 gives me 2400 rpm at 80 mph and 21 mpg on the highway. If your traffic is stuck around 60 mph though, you're high in 4th because the rpm's are too low (1800)for 5th.
Unless the track has a really long straight, I can keep it in 4th and never need 5th on the track. It's just for the highway.
