I was looking into some 3.55s or 3.73s but I wanted to know what the rpm's where at highway speeds say like 60,70,80 since I drive alot of county roads and highways. Thanks.
The difference in RPMs on the highway is so insignificant it should not be a factor in which ratio to get. I have 4.10s and love them on the street and don't mind them on highway.
Go with 3.73's. You won't be disappointed. I had 3.55's and they are great for hwy but 3.73 will wake the car up better. Country roads-3.73. Lot's of Hwy go 3.55's.
Yes, 3.73s. You'll never notice the highway difference in rpms 373 vs. 355. There isn't that much difference. Since you're changing them out anyway you might as well go 3.73.
