What ratio were you thinking would be good? 3.73:1, 3.42:1 or taller?Has anyone changed the rear gear ratio? Almost all of my driving is on the freeway and I would love to have the car running at 2,000rpm on the freeway instead of 3,000 or 3,500rpm. That alone should improve the gas mileage and lengthen the life of the engine. Yes, I might have to downshift into 4th once in awhile but it would be worth it.
There are many rear gear ratios available for my Mustang but what about the smart?
I have 70 series tires on order for the back to help BUT that will not drop it to 2000 rpm. I live at 4500 ft elevation and drive 54 miles to work which is a sea level. I can drive the entire way at 1500 to 2000 rpm no problem. Going home I might have to drop into 4th gear to climb the 4,500ft but 1st gear is almost worthless. I shift out of 1st gear within one car length.
Come on, the car doesn't have the power to pull a sick wh0re off a piss pot already even with a turbo and you want a taller gear! :rofl:
