Thanks sabongi :)

This issue has been covered. We have been shaving the center diff since we released our kits and never had a single issue. 12t clutch bells aren't recommended since they use smaller bearings (not enough material for the teeth). We use 13t all the time though. No clearance issues with pinions, but they don't provide any shock protection. The 36mm mount has more clearance since it puts the motor a little lower, but we're not seeing too many 36mm motors in 1/8th scale anymore .
