Yeah I know they make a different motor spacer but you are limited by the motor screws regardless. I might have a way to fix the limitations just have to spend time in the shop with both time and engineering.
I didn't know if there were different internal gears or newer smaller spur?
3.37 is achievable with 52/72 64p pinion/spur and 39t ring gears, haven't heard of anyone going lower than that. Maybe try cranking up the motor timing then see if it is still necesary to start modding
A new pair of milter gears with a different gear ratio would solve alot of the gearing issues, just need someone to make them
