To help elaborate on what Chris, apalrd, and I were talking about, I urge you to read "Drive Train Basics" by Chris Hibner and the accompanying drivetrain calculator that goes along with it created by Mark Kramarczyk. Use your CAD to plug in your distances into the calculator.

This may prevent you from making somewhat of a very silly and obvious mistake.
Drive Train Basics: How to be sure your robot will turn

Please at least read through Chris Hibner's paper as it includes the physics that you need to look over. Pay close attention to changes in LsubTW

For some reason I have a feeling you're confusing the difference between the advantage of a "short wheel base" (wheel to wheel distance) and the distance between parallel wheels. Once you go through the pdf you'll see what I mean. Have fun.

PS- Non driven wheels are wasted weight and wasted force. Just fyi. I'm still not understanding the rationale you're giving but good luck! Nice CAD.
