Learned about the Durametric and setting ride height on the 6SpeedOnline Cayenne forum. Re-calibrate the ride height like you would if you had to replace a sensor. Only can add 25mm to the actual height measurements and it lowers the ride heights by 25mm. One guy used it to raise the ride height to fit bigger tires. The Porsche docs for measuring points and heights are on the internets. It is 190mm front and 236mm rear ±10mm. On my CayenneS with air suspension we lowered the front by 25mm and the rear by 35mm by putting in the heights of 215mm and 271mm.
Looked pretty good to me...
Also made it so on the Low Level elderly Mom could get in and out easier than even a car.
There is a tutorial for lowering the ride height on 6Speed that goes thru all the steps but doesn't tell what the settings are supposed to be. Had to google to find the Porsche specs for that and the points on the suspension you are supposed to measure to.
The instructions for all the stuff you can monkey with using the Durametric is in the manuals on their web site. It is supposed to do everything the PIWIS can do.
