Wow, thats a ton of lift for a G1. My two biggest concerns would be the amount of flex that is possible on all of the components, I would be thinking of a way to stabilize and eliminate the possible twisting motion. My second guess is that because of the radical angle of the tie rods you will have a huge amount of bump steer. Most of us don't use this much lift on a G1 because no matter how much body lift you have only the tires get you more ground clearance. My lift is 5" and I'm running 22s easily and I don't know many who are running more than 6" and squeezing 23s. If you really want that much lift I personally would consider an ATV front end for safety sake. Just my opinion, check out Slonomo's build. Good luck
