The only solution seems to be solid sub-frame and diff risers from PBM. This is not ideal because it is not a simple mod to install/uninstall and solid bushings will increase NVH.
1. How low do you need to be for this to become an issue?
2. Do rear lower control arms that lower the shock mounting point like PBM or Stance keep the diff higher and help preserve axle life? If yes, what are the downsides of lowering the shock mounting point like this?

1. It's not how low, but the range of motion you're using. A low car with very little roll won't be stretching the axles.
2. They do not affect the axles.
