I agree too, as long as you're looking for MPG. You could even go 3.55s, but that a lot of work just to go up 1 size. But if you really want performance and don't care so much about the cost
of fuel, go 3.73s. If you ever get a OD, those would still be good or you could go up to 4.10s like I have. That being said, it's a lot of road noise with that low of gear.
