A disc clamp assembly and method for balancing a spindle hub assembly within a disc drive utilizes a base piece, a balance ring retainer piece and a balance ring. The disc clamp base piece is positioned on the top surface of the rotatable spindle hub to secure a disc stack to the spindle hub. The balance ring retainer piece is attached to the top surface of the base piece and defines a peripheral rim for accepting a balance ring. The balance ring has a predetermined mass to modify the center of gravity of the spindle hub assembly toward the central axis of rotation for the spindle hub.
