[SCOTI]

We know though that the C10 is a different monster all together.

Something that struck us as odd is the OEM C10 spindle pin is smaller than the MII pin. So basically the I/D of the C10 bearing is smaller than the MII bearing. Although the C10 bearings are larger overall, both width and O/D. If GM felt the pin was suffeciently strong enough, who are we to argue? We will base our new spindle pin dimensions off the OEM pin. Ours will just be made out of Chro-Moly. This way replacement parts like rotors and bearings will also be OEM.

While this sounds logical.... Is it?

Wouldn't GM have likely based decisions of the 'pin' design & dimensions w/the vehicles anticipated use in mind which likely wasn't near what the current trends are (autocross specifically). Just wondering out loud here. Obviously you guys put alot of thought into what you design.
