Yes, 5160 is same as 5100, just adds a reservoir.
Good luck waiting 2 weeks, you'll keep second guessing which setting. Don't think you can go wrong with 3rd or 4th setting. Can't recall if your end goal was larger tires or just to lift the front end/level. I think I would be happy either way.
I'm still liking mine. I never liked how low the front end is on a high country with z60 suspension.
I'm having a hell of a time trying to pick rims. Originally wanted Black with machined/blade cut/milled look. I think I have to much chrome and it might look odd. I don't want to start changing out nerf bars and door handles. Starting to think I can't go wrong with chrome wheels. Tons of conflicting info on what tire size will work. Hoping to save $$$ and order wheels, tires, tpms,lugs and balance online. I can go into it saying I'll make them fit. Removing lower air dam and some zip ties is no big deal. Want to avoid cutting metal.
