I have a couple questions regarding the lift? First of all it says that they dont recommend it for street use?? Is it street legal or just not recommended? I have a 4runner and it says to use rear fiberglass for 35in tires? Can i get rear fiberglass for it or should I stay with 33's? How do you like the deaver springs in back that they offer?? Do you run your shocks through your bed or are they still under the truck??
