I just did this using ISTA Plus. It worked a little different than everything I have read before.

I connected and chose the appropriate section.

It asked me for rim size in inches and then the measurement in mm. It separates front and rear measurements. I selected fronts and put the appropriate measurements in. Then it directs you to the rear.


My truck was off right to left on both axels by an inch in front and 1.5” in the rear. The first go, the program said the front was in parameters and didn’t allow a change. The rear was far enough out..

I went back to the front and fudged the numbers to get it to level.

Then, I wanted to drop it 30mm...

After the initial calibration, I started the truck exercised the suspension through all three settings and then returned to the middle ride height. The ride height was 711mm all the way around (this is what it went to after calibrations).

Then, to get it to lower, I fudge the numbers left-to-right. First, I chose front axel and put LF at 741Mm and RF 711mm. Then the same for the rear. I hit continue and allowed the truck to take the difference. I started it again and ran it through as above.

Then, you go back in and do the same but switch the 741/711mm numbers. The overall result is a lowered truck at the middle position (really all positions)

I measured everything and it ended up being 27” from the bottom lip of the rim to the fender. The RF was 26.8” and that is due to me fudging the numbers in the beginning because the 1” was w/ in tolerance.

Overall the truck looks amazing and is slammed when I put it in the lower position when parked.
