One is 12 inches wide, one is 11 inches wide. any smaller smaller, you are gonna be screamin down the road burning gas. If you have the 35's i would just keep the lift. I got 35's and stock 3:73 still. I am gettin 8-9 mpg. 4:56 is my nxt step.
Tanz do you have a tune? I'm asking because I have a 6 inch lift and 35's and I'm daily driving getting 14 miles a gallon, with stock 3:73's.
