I have played with diff oils a lot and have found I prefer lighter oils because when ever I go 10k or higher it makes the car to twitchy for me. My set up right now is 5k front 3k rear
Front
Long link 2 mm washer on knuckle
Middle on tower stock caster blocks
Inside lower hole on tower for shock position
Out side hole on arm
Rear
Middle on 1* hubs
Inside lower on tower
Inside arms with 2 mm in front and 1 mm in rear
Hubs forward
3 right side up on toe insert
2nd hole from top on shock tower for the shock
Inside hole on arm

I'm leaning towards 81/26 combo but please bestow your knowledge on me.

10k/10k
10k/5k
7k/3k
I know that many other factors play into this but I would like to get a good jump on things with diff fluids right off the bat.
No racing, just playing around on less than perfect track conditions.
Thanks All
