The truck is a 88 k5 with a 6 inch and 35x12.50's... i want to run 36x13.50 iroks for all the serious stuff and run my old 35x12.50s during the summer or when i'm not goin to be wheelin. My rig is a dd/ weekend warrior and spends about 50/50 on and offroad. I try to keep my sh$t in tact but still wheel it pretty hard. If i get the 36x13.50's without a lift or cuttin they will definetly rub because my 35's rub a little when i'm fully flexed and have the wheels turned. I want to keep the body as it is but don't want a higher cg. How much will a 2" body lift raise the cg? If it is going to be noticable then i will cut the fenders. What do you think? when you guys cut the fenders did you follow the factory line? I want the wheel wells to look like they do now as far as general shape and figured that would be the best way to do it.
