That's why I'm not doing gears... I don't want high cruising RPMs. Anyone done 4.57s and some sort of taller 6th gear swap?

The issue of higher rpm's w/ gears on the highway is highly exageraed. I ran 4.77's w/ a comptech setup and it was awesome. 1-2 was pretty hard but it pulled much harder at low and mid rpm's that a sc w/ stock gears.
