Increasing wheel/tire size would have the same effect. And truth be told, if I knew someone with a big honking set of 14 or 15 inch wheels that would fit our odd-ball bolt pattern, I would like to try them first and do some calculations to see whether or not I'd be happy with the transmission swap.

I probably wouldn't be doing any of this if I didn't have the transmission. It was essentially free.
