yeah X3, I'm on 3.25" lift with a SC and should of gone closer to 35's

 

Go for a light 35 or even a 34. 33's will look small with 3". I went 35s and My gas milage is fine and so is passing but its also a rubicon with a manual.

 

Here are some pics for reference...

2012 (4.10 gearing) 33" no lift just a 1" spacer to eliminate the factory rake



2008 (5.13 gearing) on 35s with 2.5" TF coil & 1" Body Lift



2008 with 33" (looks kind of "off" so I upgraded to 35s)



33s with just a 1" body lift




If you choose not to regear then get 33s with a 1.5" or 2" lift and drive with the O.D off. When I ran 33s on the stock 3.73 gearing, it was bearable but I was not satisfied. After regearing to 5.13s it made driving with 33s fun and then acceptable when I upgraded to 35s. Because of the nature of the 3.8 and the 4speed auto a regear is a must if running 35s. Take it from some one who has "been there, done that".

Now the 2012 with the 4.10 gearing and 5 speed auto it's a whole new ball game, it pulls those 33s with ease and holds its gears even on inclines....
