Adding droop (removing travel limiters in the shocks) will allow the car to land better but it will be easier to traction roll on indoor clay. If you're still having issues, try making/purchasing 1.5x2+1.1x2 flat pistons. They control the high speed dampening pretty well.
Run a shorty and you shouldn't have a problem bottoming out. My son and I run 22mm ride height indoor high bite, he with the 1.6 pistions, 30/27.5, kit springs, me 3x1.4 pistions, 35/32.5, kit springs and it's no problem. That's with 7 grams in each rear triangle.
Bump it up to 24mm for outdoor, add another 14grams of weight in the battery tray and again, no problem.
