i'm trying to decide between 4.10's or 3.73s for my 03gt automatic n/a. I know the difference and everything but the only thing im worried about is being at high rpms on the highway with the 4.10s. anyone here with 4.10's automatic that can let me know what rpms i would be at 80mph? thanks!!

randy's ring&pinion ,on his web site they have a calculator..gear tire size = mph

I say 3:90s

3.90s or 4.10s

unless your on the high way 24/7 then maybe 3.55s or 3.73s to be a little nicer on your wallet
