I did a little experiment to measure a bunch of locations under my FJ as I recently transformed it by adding larger tires, then a front lift, then a rear.
I took pictures of all the locations and then put the measurements into this chart.
Net results:
* Adding 285's increased my ride height by just under 1"
* Adding an All-Pro front and rear lift (adjustable front set to about 2 1/2") has given me a total improvement over stock of about 3.4"
* My low point used to be the skid plate just aft of the oil pan
* After lifting my low point is now my rear diff (as expected)
There are lots of variables in this such as the exact spot it was parked in my driveway (cement isn't perfectly level), how much cargo/gas was loaded, PSI in the tires, etc... so that is why there are some variation in the numbers. But, all in all it is pretty accurate.
I noticed I didn't have the stock ground clearance that Toyota claims in the ads. I forget the exact measurements but changing the PSI on my MTR's from 35 down to 15 did reduce my clearance about 1/2" or thereabouts.
