Height High
I always wondered exactly how much the "Height High" button would raise the car. Yesterday I got a chance to use it because they're repaving the road near my house. For anybody that's curious, it raised the clearance from 7.5 inches to just over 8.5 inches (in a 2015 AWD F-Sport). Even though it's only just over an inch, the car seems noticeably taller. Oh, and the ride seems a little bouncier. Nice to have when you need it; but I turned it off as soon as I didn't need it due to the ride.

Yep, almost 1" exactly were my recordings too.
Fun fact: The automatic lowering of the vehicle at sustained speeds above 65mph is also 1". So, if you don't want the vehicle to lower itself at speed (snow/water on the roadway) you can simply push the height high button when sustaining speed above 65mph.

Exactly. The intent of Lexus was improved aerodynamics at speed for our landyachts.
Pushing the Height High button above 65mph will keep the car at the Normal height, neither raising nor lowering the suspension. If you have the Data Systems Controller, the harness that attaches to the back of the navigation automatically engages Height High above 45mph in order to lock out the automatic lowering of the vehicle. You wouldn't want to be on 4 and have it drop another inch when your flying down the road at 70+ MPH, the suspension characteristics get extremely dangerous and ground clearance would be nill.

In order to optimize the stance of my car, I went through fairly extensive measuring of all the settings. You guys are all very close and hitting all around what I measured.
On Height High, I measured an average of 0.820" increase in height. Broke down to 0.969 average height increase in the front, and 0.672 average height increase in the rear.
Before I recorded measurements I jounced the suspension through a little "course" and always returned to an exact level spot, to get a truer reading.

I measured to each of the 4 fenders. I held the tape measure touching the ground, up beside the center of the wheel, to the fender. To the fender liner edge on the fender well (from memory). It made it very consistent.
