Based on the online calculators im going a little over 2000 rpms with 2.93s, almost 2500 rpms with 3.55s, and a little over 2700 rpms with 3.90 with my tire height and tranny at 55 mph. My jeep patriot does about 3400rpms at 70 on the freeway so 3.90s I guess isn't so bad since most of my streets in town have a 35-45 speed limit. Besides 3.90s are lower than 3.55s so wouldn't it give me have a little better acceleration and more push to the seat? but everyone seems to be recommending 3.55s
