My droop settings is upon your post.
For the oil weight, I start with 30wt ~45wt No.2 piston with rubber tires on asphalt surface.
If the car feels like response too quick, or feel slow on some high speed corners (large diameter turns), or car looks like keep bounching on everywhere. I will go 10wt heaver oil and try it again until I like it. If feels too much, become sluggish or bumpy (tires always off the ground crossing bumpy sections), I will go 5wt ligther oil weight until I like it.
hehhehe.. setup a car is a little bit like cooking.. make it yummy ae..
Mainly for me, I use 30wt oil when the track is small and tight corners track. If track is large and a lots of high speed sections, I will go with 45wt.
