Hi all the main issue I think really is the steel suspension needs to be able to get to 9-10 inches of clearance to really go crazy.
The Cayenne with Steel is about 8 inches.........Jeep Wrangler X(which I owned at the same time as my Cayenne, is 8.8 from factory). My wrangler fell apart in the exact same time I owned the Cayenne and the Jeep had only 94k miles and the same loving service I gave my cayenne.......only the cayenne did not eat up 2 coolant systems......radiator, thermostat, cracked head gasket eventually and the cheap interior falling apart........but the jeep was a basher if you needed a car to rub down trees on a trail.........it did not have the same traction control as the Cayenne nor the stronger engine. i had inline 6's on each, the Cayenne having the VR6 setup.
Not sure if the Cayenne setup is compatible to a either a body lift or suspension lift........and how the drive shaft is angled.........someone previously noted it, might not work.
Ground clearance: 8.54-10.75 inches

The 10.75 inches for air is in line with factory jeep front clearance.
I guess remove front and rear valence like that GORM rallye cayenne and I think you got it.
And attach a lower guard. (1k)
However, I see these 2wd and 20 year old plus Turbo diesls cars with a mild lift and a/t tires making treks on Expo. They all have decent interior room, roof rack for field essentials, and just gas and go with extra gas and spares attached.
I think a barebones stock V6 Cayenne with steel, can go most anywhere but rocky trails and deeply rutted backcountry log roads/fire roads.
To gut one this young is still a bit out there when considering light overlanding/camping.
And I see them in the 15k range, a jeep with that age and mileage would be 5-8k range? I sold mine for 7700 last year to car max......
Definteley cheaper to keep the jeep running but it was unrealiable as a DD once issues appeared.
I am sure a good jeeper on here could and would keep one going so please dont take it as a knock against Wranglers, more like a bump up for Cayennes for reliablity (V6) eating tires oil and gas only with strong drive train, center/rear diff and 250 hp.
