6112/5160 set up question

I want the truck to sit as close to normal stock height as possible but also level with the rear. Don’t want bro lean or ass up.

To achieve this do I need the circlip positioned on the lowest setting i.e. Position 1 (zero lift) or Position 4 (1.6” lift)?

I read 1.6” is pretty much level.

Should I position the drivers side clip 1 position higher to combat Taco lean?

I do not intend to change the rear leaf springs and I’m not carrying a lot of weight in the back or towing. Most of my off road driving is just mountain bike shuttling.

Thanks in advance.
