the track im on is set up for 8th scale 4wd electric and nitro. So the track gets heavily rutted and blown out. I am running a 10th scale 2wd short course. I like to run drop close to the same front and back but to get there i am currently at front , no internal spacers, unscrewed eyelet two full turns. At back i am 6 internal spacers, .030 each to be somewhere close with droop front and back. I have a corner i loose contact with dirt and get thrown off, maybe just need to learn to maneuver corner better. I also get squirrelly after a couple landings.
Another option is experimenting with a dual rate pistons? It is possible that you have enough droop, but rebound might be slow. If this is true, then adding more droop will not fix anything.
