How is the break-over angle calculated? Using the published angle of 21 degrees, the published wheelbase of 112.2 inches and running some geometry I should have about 23" of clearance from the ground to the frame half-way between wheels. I measure about 11" in the same location. Back calculating angle from the 11" clearance gives about 11 degrees. Stock truck. What am I missing?

Ah I see. I missed the marker indicating which angle was being measured. You're right that is not intuitive.
So a stock LC has only 11" from the floor to the frame at the center?
Yeah about that. Frame was ~11.5", Gas tank skid ~11".
Interesting enough to dig into. In that AUS brochure linked by @Madtiger
The GX "stripper" trim is a 5-seater, cloth, no roof rack, and no sidestep. Curb weight is ~220lbs lighter than any other variant. It would be this model that has the best chance of putting up the best angles. Yet in the comparison table, it has the same angles as every other variant. Numbers that agree with the US brochure number, yet conflict with the earlier page posted above.

Funny is where they're taking the angles depicted in the picture. To the body side-molding rather than the chassis frame. That would certainly account for the difference. Just keep the rock or obstacle over the body line... crunch

Or the specs in the listing is incorrect.......and is copied over to US brochure?
The point from the picture...could be just poor graphics drawing?
Just too many inconsistencies in what Toyota states. Very confusing.
In your first post, the table shows that 2008 LX has same approach and departure angles as LC of same year, right? Given that both have same tire size (just different rim size), same wheelbase, same underbody......why is the breakover angle so much better in the LX (even in NORMAL mode).
My theory of pimple popping kid doing the specs......
Mine is sitting in H right now, thought I'd measure. The tires are at normal (street) cold pressure. I have an aftermarket rear bumper.
2009 LX570 on 35s.
Rear - 39 inch horizontal, 22 inch vertical -> 29.4 deg (Rubicon 4-dr 37deg)
Front - 32 inch horizontal, 24 inch vertical -> 36.9 deg (Rubicon 4-dr 44deg) (measured from tire touching ground to the vertically flat part where the license plate is mounted, not to the lower part which angles back, as that angle isn't the first contact point. Nor are my recovery points, though they are closer, but I think this measurement needs to be standardized somehow as there are several different options, unlike the rear which is straightforward)

I'm surprised the departure angle improves by 20% with the 2016+. I can't see how that's possible with the same length, wheelbase, and height. The bumper barely fits around the frame (hitch) so it's not like they could shorten or raise it much even if they've wanted to.
Does anyone know whether sliders increase break over angle for the lx? Or does it just provide a level of protection but keep break over angle about the same?
Increase for sure. The factory running boards are the lowest point between the wheels for sure. They hang down 2-3” below the frame.

What happened to 2012? Is it 29 or 25 or did they skip a year? : )
2012 MY (2011) was the Tsunami year for Japan and production was paused until 2013 MY update. There may still be some 2012's in other markets, but I don't think we got any. Similar situation if you're ever looking at FJ's as the special edition for the year was produced is lesser numbers with less features than normal (also called the NSSE, not so special edition).

You all are a wealth of knowledge, thanks!
My LX570 seems to have more ground clearance than 8.9" in high mode. This must be a typo. There's no way it's less than 9" in high mode in stock configuration. I remember someone once posted an excel spreadsheet of these angles/ground clearance etc with different size tires, but for the life of me I can't find it. Anyway, 8.9" doesn't sound right on an LX in high.
Where is ground clearance measured? Bottom of the rear shock mounts? Those would I think be the lowest points.l and won’t change due to AHC

It's going to be the lowest point. Since suspension lift doesn't change the ground clearance number in the table, you can assume it'll be measured somewhere along the rear solid axle which clearance does not change regardless of suspension lift. It's going to be the low point on the rear axle, likely the differential. The rear shock mounts do hang a bit lower still so if I had to guess, it's not that, and the manufacturer probably couches that to be in the shadow of the rear wheel barrels in a stock cruiser (which doesn't have aggressive offsets exposing this feature more).
Solid axle clearance is only affected by tire size. Which is why tire size is such a huge factor for off-roaders.
Makes sense...
Correct. In other words, measured from the pumpkin.
