Be mindful that adding droop also increases weight transfer so the car will probably get harder to manage in turns, especially higher speed ones.

If you’re happy with how it’s running now, why not try going one step heavier on your shock oil? That might help with the harsher ruts. A 1/10th scale car will never glide through 1/8th scale ruts, but you may be able to get it to “bounce straight”.
