Nota4re,
Oh yeah. :bow I think you have gone to a different level from me. I just take my Porsche on the occasional forestry roads with a few steep ascents/descents, minor rock gardens, etc. Probably have to do some serious mods to do this. The Porsche has a locking longitudinal diff 4WD (AWD on the road), but I did not get the optional rear locking diff...oversight on my part (Porsche dealer says that they cannot add this option now). The nice thing is that I can raise the height from about 6 inches to close to 11. On the road I take it at the lowest level.
Like the pics!
