I like the Maxx slicks but is it possible to prevent them from balloon so much? I would need a much larger spur to run them. What are my options for spurs other than the Revo stock spurs (36, 38, 40T)? I think something around 46 would be the largest possible M1 gear that would fit. 32P would be acceptable, too.
Yep 46t is the largest that will fit without touching the diff output. You could try the jato spurs, 54, 56, 58t and 32p pinions. The spurs are .8 mod, but they work fine with 32p pinions.
