Looks sweet, why not go to 35's? What coils are you using for the rear? Mind going into the grsII transfercase for the non Zuk owners? I dunno what it is.
From what I've heard, 33's are the "magic" tire for sammi axles. Any higher and they tend to snap like twigs. The coils are from a set of eibach coilover shocks. They are 175lb ones, but I'm seriously thinking about dropping to the 150lb ones.
The grsII is a 4.89:1 case with the ability to have 2wd low. I don't plan on going to toy axles now because of the locker setup. I also want to keep it as simple/cheap as possible. All of the other stuff was done by the PO. I've also heard from a couple of witnesses that this rig hung right in there with all of the other built rigs at the hammers.
