This is exactly why I’ve been interested in the topic. With specific interest in keeping the roll steer properties.I hope nobody is thinking I have anything against lowering the PHB and also reducing the amount of rear bar. I don't, not where you might have a clear reason for doing them together, anyway.
Offhand, the only reason that comes to mind where you would do those together is where you're specifically looking to improve acceleration traction on corner exit. Not for tuning understeer-oversteer handling balance unless you're also planning on running significantly more rear spring to make up for what you gave away in bar.

Having two cars that are setup on different ends of the spectrum and driving them back to back make me wish for tuning that allows for more of both roll steer and ability to put power down.
