Im thinking of switching my gears from 3:73 to 4;10's or 4;56's and installing a shiftkit while i was at it, i guess my questions are, with a 33in tire what would be the best gearing to go with, and how would the performance gain with the gears and shift kit be? and how would the drive ability suffer? im getting close to 23mpg now if i can still get 18-19 ill be happy.... thanks guys.
