YAY! Everything went as planned!
Huge thanks to TeCKis300 and the many others who provided detailed info.
305/55-20 on stock rims (+60)
1" Bora spacers
Removed front mud flap.
Tires fit great, no rub, look awesome, love it!
Shop used TeCKis300's instructions for fitting larger spare, went great!
Here's some quick pics.
I do feel a tiny bit of vibration in wheel at certain speeds.
Don't know if it's the spacers or tire balancing.
Thoughts?

Looks awesome! Did your shop do anything with the rear studs (ie shorten) in order to use the 1" spacers in the rear?
Another beast! Great job.
The vibration can stem from a few places. In order of most likely:
1) tire balance
2) wheel mounting
3) spacer mounting
EDIT - What @bencallaway mentions with the studs as IIRC, the '13+ wheels don't have pockets for stud. I personally would grind the wheels for clearance rather and shorten the studs.
I would suspect #1 first. Rotating the suspect tire to a different position can help isolate the tire that needs balancing.
#2 can be an issue also, and can be done while troubleshooting #1. Some shops torque the wheels on the ground, which allows the wheel to be mounted just off center. I prefer to torque them in the air, in sequential tightening passes in a star pattern, while also spinning the wheel to allow it to center better. I believe your spacer is hub centric, but there's still just enough play to cause it to mount off-center.

Should they have cut the studs?

Depends - pull the wheel and see if stock studs are extending past the spacer (they likely are). Does your wheel have room behind it for the studs to fit into, or are there pressure marks on the wheel.
Maybe. That’s why I sent you the blue ones too. You have the same wheels I have and on my truck the studs extend beyond the spacer so the wheel bumps in to them when you remount them.
Pull the wheels and see if the studs left an indentation on the wheel where they protrude the spacer.
Looks great !!
Not sure if they make this grill for UR LX......
I have a GX & swapped it out for the F Sport
Interesting...I don’t feel the vibration now that I’ve driven about 40 miles.
Just got the Slee blueberry front bumper installed on my ‘07 100 today at same shop so I asked about vibration & studs. No trimming of studs, but I will have them check for an indentation. They’re a wildly popular offroad shop that only does Toyota & Jeep, so I’m comfortable with their work, but we’ll see.
Said they’d seen new chunkier tires settling in causing small vibration, since it wasn’t doing it anymore, said bring it back if problem. Plus I increased psi to 36-37 from 33....per post I read here for the larger tires.
The hundy’s going to be my offroader, so no front bumper on the LX.
They removed the side steps on the 100 and my Rocky Road Super Sliders should arrive in next 2 weeks, then I’ll decide on a roof rack.
TBC......

So mine’s a ‘10.....does that mean my wheels have a pocket then?
Well, after about 400 miles, driver rear wheel literally almost fell off....had super weird vibration and feeling, pulled over, 4 lugs on rear driver wheel were FINGER loose, and one stud was snapped off. Just like many mentioned above, the shop says stud is protruding a hair beyond spacer. Recommended wider spacer.
I forgot to ask them if the wheel shows a score mark....I will tomorrow.
I can have them install the 1.25" spacers on rear.
QUESTIONS:
~If NO score mark on FRONT wheels, is it acceptable/safe to leave the 1" spacers on?
~What does having the 1.25"/1"spacer combo do to the driving dynamics and the wheel geometry? Bad idea?
~Is it really OK to grind the wheel a bit to make clearance for stud?
@bencallaway recall what brand the 1.25" spacers are? (They're not with me now) Shop sells Spydertrax.
Thanks all for your help!

Oh man! That's a freaky situation and glad it didn't result in much worse.
To answer your questions
- If there are no score/witness marks on the front axle, you're fine. But I doubt that would be the case as I believe all the studs to be the same length between front and rear axles
- Optimal wheel offset for scrub radius geometry is partially dependent on overall tire diameter. With your current tires, a 1" spacer (~35mm effective offset) puts things a bit closer to optimal (~45mm). Though 1.25" (~28mm effective) won't be too bad.
- Yes, it's okay to grind the aluminum wheel as there's no structural concern at that part. Just enough to clear the studs where the witness marks are.
That said, I would consider all the studs on your wheel spacers to be compromised at this point. Particularly the one where you found bolts loose and a stud sheered.
1.25" spacers would be a reasonable direction. May create a bit tighter clearances at the front as the tire steers.

1.25" spacers in the front do require a decent bit more manipulation as the front flaps will have to go and part of the internal running board.
I have zero clearance issues in the front with 1" spacers but the rear did require 1.25". Hence my reasoning for sending you the extra spacers. Sorry this happened. I did everything I could to make it clear to you that the 1" would not work in the rear. I'm surprised your shop didn't notice the studs protruding beyond the face of the spacers.
I beleive the blue spacers I sent you are spidertraxx or a good knock off.
I'm running 1" in the front and 1.25" in the rear as are many others here.

Not your fault, I expected shop would have noticed it too and advised me, as I took both the 1" and the 1.25" when I had them installed. They knew I had both sizes. 
I'm po'd!
So it's possible the front 1" work fine....but I want to know if there's score marks on the back of rim.
Sounds like you ran 1" front and 1.25" rear...so there's no issues doing it that way?

Sounds like @bencallaway has nailed this setup. It's a pleasant surprise that the 1" spacer works with the studs on the front axle, as that's where the offset plays into suspension geometry. The rear won't care if it has 1.25" spacers.
Ideally, the front and rear axles have exactly the same track width for things like sand. But there's likely not enough difference to matter.

Correct!
Shop had some 1.25" Spydertrax in stock so tried them on front....say NO rubbing. I told them to RE-CHECK and make darn sure it doesn't rub in AHC-Low. Waiting on answer.
Wondering how bad it will cause water and mud to spray up on side because it's just slightly outside wheel well.
If I have 1.25" all around, what's that do to the scrub radius, handling etc...?
Gotta go up to shop to eyeball this myself before I decide.

● Got shop to shave the front studs a tad, so no problem on front with 1" spacer. They wouldn't shave the rears however.
● Tried 1.25" spacer on front, but rubbed in low AHC.
● Have 1.25" spacers on rear until I take it to my mechanic buddy's shop Monday. Prefer to go back to Bora 1" spacers on rear, so shop will shave studs on 1" spacers and mount.
● Now, to complicate the matter, I want some other Lexus LX rims I've found, they're from an '08 LX. 20" x 8.5" +60.
● Recall my LX is a '10 but my current rims appear to be from '13-'15 model year. 20" x 9". We're not in a position to get under there to look for offset
● My online research shows (apparently) only two offsets available...+35 in chrome, +45 in hypersilver....mine are hypersilver.
● If they're 20x9 +45, and a 1" spacer, and I go to 20x8.5 +60, will the 1" spacer be enough, or will I need the 1.25"?
● Also rim is 1/2" narrower, how will that affect it re: rubbing with the +60?
