Generally, bump rubbers (which are just another spring) are used to 'help' with the aero loads, but also third or center springs. Bump rubbers can be a problem if track bumps cause you to hit them at the wrong time. Third springs are the opposite of an anti-roll bar. They act purely in heave and have no roll-stiffness contribution. If one makes the 3rd spring too stiff, though, it causes other issues. So what do you end up doing?
3rd spring as stiff as you can without it getting difficult to drive, bump rubbers as stiff as you can, but with a large enough gap that you're not touching them inadvertently, and the rest of the corner stiffness comes by way of the corner spring. If you need extra roll stiffness, then add an ARB. If you don't, remove it.
