I'm definitely not building this thing with MPG in mind. I'm assuming I'll be in the single digits when all is said and done... lol. I just think it would be better on the motor and I don't really want to hear the engine droning at 2800 rpms while cruising down the freeway. My plan is to have BFG Radials 255/70R15. I think it's about a 29 inch tall tire.

I realized why I originally thought the lowest gearing I could have with a 3 series carrier was 3.42. If I were to put in a limited slip carrier, that's the lowest I can go because a 4 series won't fit... now I have to decide whether I want 3.73 w/o limited slip or 3.42 w/ limited slip... or try and find a 4 series carrier rear end...
