i did a bunch of searching trying to figure out how everyone was electronically lowering their x5's. I saw that most were using dis/gt1 which is the previous generation bmw.diagnostic software. Looking into that seemed to be too complicated. Being a technician at a dealer with access to ISTA bmws current gen software I thought why not give it a shot seeing as how recently I had some experience setting/calibrating ride heights for replacement of a sensor.
Using ISTA/D 3.0 I lowered the 4.8is about 1.2" all around
Starting heights
Front 705mm added 35mm to lower approx 1.25"
Rear 705mm added 30mm to lower apporx 1.2"
