Do not get ceramic bearings ever. Obr will even tell you that. Unless you plan on rebuilding every race like top fuel dragster nhra guys do. Stick with nachi and stock seals.
 
The only reason I wanted a balanced crank is because ill be running a carbon chassis. I don't think carbon will soak extra vibrations like aluminum will. I believe aluminum is more rigid.
 
These hook up in my field. Very short grass with soft ground.
But I agree z. I think the ubers are better. Would like to see the weight of a uber tire compaired to mx’s. Weight is key here in my build especially rotating weight.

Omg! Got parts in today. Ddm spur weighs a ton. Its definitely going to my buddies machine shop for holes. Retarded heavy. Kind of ridiculous in my opinion….
 
I just don’t understand why there not lightened. The spur is a half pound. Crazy. 8, 1/2inch holes in it would substantially make it lighter.
Spun weight. Hell it even makes it harder on the brakes stopping it. But I guess thats the point. Money🤦🏼‍♂️🤦🏼‍♂️🤦🏼‍♂️🤦🏼‍♂️🤦🏼‍♂️🤦🏼‍♂️🤦🏼‍♂️
This is a mod in my opinion someone can make money on without having to change an entire clutch system on. 🤦🏼‍♂️
