7.5 Differential Kit, 6 Spyder Questions

[Serum]

Yeah, the normal e-maxx diffs are 37/13 and the 6spiders are 43/13. You need a larger pinion, or a smaller spur.
a 12T pinion or a 82 spur. Eversince the spurs are not available that size, you'r better of getting a 12T pinion.

Serum, you contradicted yourself there.

He's running 14/70 right now. I think a 16T pinion shold take care of it.
