2.76 to 3.91's SG

guess it depends on your driving ..if you drive the highway for any long distance I would wait till you go with the 6 speed to run 3:90 or lower type gears ..there very nice on the street but a bit much if your on the highway a lot ..and with gas at $4 its expensive cruising.... changing rear gears not big deal other than lifting that chunk as stated ..I know I can't any more ....getting to old and too smart
