I can't decide which gears to buy for my stock LX (5 speed). I was originally going to go with 3.55s to leave a little highway room, but I'm wondering if I'd be happier with 3.73s? I do drive my car occasionally on the highway. Anyone know the difference in cruising RPM between the two (say at 70 mph)? I had 3.73s in my '90 hatch, but it had a Tremec 3550 with a lower than stock 1st gear ratio--I burned up my tires in 1st gear even when I didn't want to.
