50t slipper diff?

[lincpimp]

Hard to get 5.5:1 reduction with a 46t spur! That would require an 8t pinion, and those are only available from individuallipocells.com, and are made of unobtainium, so they are perpetually out of stock due to the limited (!!) quantities of said material.

Plus having a larger diameter spur will aid in fitting larger diameter motors (especially with smaller pinions), and also give needed clearance if mech brakes are to be employed. Plus some guys just like it big (Mix-A-Lot?)! And some also still run crts with buggy ratio diffs...
