Yeah for a Rally or Silver State 300 in eastern Nevada.:victory:
Cole,
Did you paint or powdercoat or anodize your rims?
But as to your questions . . . (WARNING: Not an expert )
As I understand it, the Advanced Offroad Technology Package with the rear differential lock was optional on all of the models: S, Turbo and plain (V6) Cayenne. The stock setup allowed only for center diff locking. However, I've looked at a dozen or so S and Turbo Cayennes and have yet to see one with the Advanced Off-Road Package (identifable by sill protectors and skidplates) and I think the option is very rare.
.
Good luck heading down this road.
Some mods to my Cayenne. Behind the front seats is an Engle 17qt fridge and Yeti soft cooler, front runner water bladder. In the rear cargo area is a Dometic 25 fridge, Ark Pak , Lift Trax , 5lb C02 tank , two Alu boxes.
Tepui Ayer.
Nice, thanks, and the size is 42x48? How do you like it?
I have the factory roof bars on my 957, not sure how much weight those can hold, they are off for now as I was thinking of puting my surco safari rack I had on the touareg directly on there at one point (good for a spare and other stuff)
