WOW that is a huge lift and yes that is the largest you can run. I have the 1.2 rear and CO's up front and run 33's no body lift, and I feel tippy at times since we are already top heavy. You can fit 35's with a 1.5 in BL and some minor trimming. Sonoran Steels website has a good write up of this information. Also 35x12.50's? I know they make that size in a 15" and 17" rim size. If you have factory 16" you wont be able to fit a 15" rim over the brakes.
