A compressor rotor includes a rim having airfoils extending radially outwardly therefrom, and a corresponding web and hub extending radially inwardly. A row of curvic coupling teeth extends axially away from one end of the rim. An imperforate support ring extends radially inwardly from the rim end for carrying hoop loads. And, a balance ring extends radially inwardly from the support ring, and includes a balance notch circumferentially splitting the balance ring.
