    Default Bronze bushing vs bearing birdcage

    Is there any advantage to bronze bushing birdcages vs bearing?

    If your setup requires more lr damping, extra friction could get you there.
    Droop isn't the problem.

    My coilover is pretty square at race attitude. I guess if it's leaned in enough, maybe you could exceeds the allowable axial load. A guy could get tapered rollers.

    The problem with bronze bushings is that they require a ton of maintenance. You need to keep them greased and clean at all times. They do wear out tubes faster than bearings also. The good part is, if they are a real wide birdcage, they won't bind as bad as a bearing cage with axle tube flex. Also, make sure if you get bearing birdcages, be sure the bearings being used are of the best quality. We used the Wehrs machine cages for years without issue.
