Hey guys. Quick question for you that have the 4:10 gears on you S197 manual. Currently I get roughly 17 mpg city and about 21 mpg hwy. I am interested in getting 4:10 gears. I drive 25 miles to work hwy only, and I don't want to sacrifice my gas milage too much. If you have the 4:10 gears, please post your mpg for me. I tried loking through the sticky, but it was taking forever to find the 4:10 mpg. Thanks in advance!
