...The difference with a Saudi Spec from what I can tell is really just the grill. ( mine is not mounted yet) All wire mesh and better air flow. For all intensive purposes it's just a ROW Discovery 1...
... I live in TN and they are pretty open to conversions. I went front channel and it went right through emissions w/o issue. They even changed my reg to diesel. ...
As for the tires, I got them the same place RN did so I paid just about 1/2 that price. Shame they are no longer available
I got them for the rims as the tires are just OK. I will use the tires until I have extra money to get different ones as I don't love them at all. Bad in the rain, Bad in the snow and only OK in daily use. They do look cool so I will give them that.
