Well yes, but I'm mostly concerned about friction. That rotating mass gain I've never been able to clock. Total weight reduction yes, but not rotating mass. Spite the theory. This is after all insanely overpowered toy cars
So how can we make these driveshafts as smooth as possible? And as long-lasting as possible?
(I have a strong feeling the ball diff solution can be improved too, but I'll not start that here...)
@AmiSMB: how dry is it? Spray or grease?
