@Furrypanda1121 B8 UCAs fit the gen 6? I’m so down if that’s the case! Where did you get yours!?
Bilstein used my 4runner Hybrid for their fitment and testing back in December. They offered me the 6112/6100 combo with UCAs for letting them use it for 3 weeks. It'll be going in next week for install finally. Not sure if its specifically the B8 UCAs or if it's a different model, I just know that is part of the deal I set up with them. The photo they sent me had the 8112 kit installed with Bilstein UCAs so I know they have something that fits, not sure when it'll be available for purchase.

Initially I've went with the 4 clip, but when I got in trouble with the rear pucks, then re-did the front on the second clip with no rear lift. That gave me 2 inch of lift(should have been 1.7 according to Bilstein) and I'm expecting to drop another 1/4 or 3/8 after a few days. It did drop 3/8's on my 5th Gen, but I had a winch bumper and winch in the front so that's that.
The tires are BFG KO3's second gen 285/70R17 C load on stock wheels +55 offset.

Your Runner looks great, and thank you for that insight!

I went out and measured my stock rake on my seven seater SR5, with 3/4 tank of gas. It's sitting at ~1.75-1.8" higher in the rear. I have the 1 inch Westcott rear pucks that will add another ~0.75". So I'm also going to starting at a circlip position #4.

You were going to run your front at setting #4 without new UCAs right? that's what I'm hoping to do and run 285/75R17 K03s.

Oh yes, I've seen this build in another thread, didn't connect the dots that was your Runner!

First off, Bilstein set up your Runner Sick!
Second please keep us posted if you find any information about their UCA offering, that UCA would be the ones I'm interested in getting.

Will keep you posted. Pickup date is now set for tomorrow and I'll have it back in another 2 weeks. Also got a little tidbit from them today. They will be testing out heavy load springs paired with the 8112s while they have it this time. No release timeline for the springs though.

Once its back Ill post some photos.

😂 I asked to see if I should keep mine mounted or take it off. They specifically asked for it to be as close to stock weight as possible so they can get correct measurements.

Yes, I think you can run it up to 5th circle with factory UCA and still get an within specs alignment, but at that lift you may want to consider a differential drop.
