I don't think you want to be compressing the rubber any more than can be helped. Clamping load "lost" to rubber compression comes out of the clamp load through the bracket side-inner sleeve-bracket side stack, which is really how this kind of bolted connection is supposed to work. Not through direct shear of the bolt as is commonly misunderstood. FWIW, this is much more critical with polyurethane bushings.
