I just bought an 08 mega cab 1500 4x4 hemi. I had an 04 quad cab 4x4 hemi with 5"rcx suspension and 1 1/2" body lift with 35x12.50x17 tires on 17x9 -12 offset wheels and 1 1/2 inch wheels spacers. I had to put the wheels spacers on to make it look correct with the bushwacker fender flares I had otherwise it looked to narrow. I like the tires to be flush to the outside of the flares. So my question is with the 5"rcx suspension for the mega cab and the same fender flares what offset do I need on a 20x9 wheel with 35x12.50x20 tire to have the same flush look. I'm figuring the solid axles under the mega cab are wider than my old 1500 ifs. any help or photos with configurations would be really helpful.
