Thank you for the info so far. I will try and address the questions.
I put the light Racing Upper control arms on with the lift and moved the sway bar forward with the spacer.
There is no rub on the coil, UCA, or sway bar.
The alignment was literally done today. The Left Front Camber 0.4degrees, Caster 2.3degrees Toe 0.06 degrees. Front Right Camber 0.4 degrees and Caster 2.8 degrees, Toe -0.01degree. Front Cross Camber 0.0 degrees. Front Cross Caster -0.4 degrees. Total Toe 0.05degree.
Wheels: I am not trying to reuse the OEM wheels. This is one of the wheels that was tested. The best that could fit on these was a 265. I DO NOT have to have these wheels. I thought the shop I went to would be able to figure out the back spacing.
There is no rub in the front of the tire. The rub is in the back of the tire against the cab mount. On a flat surface with no flex you start turning the wheel and the shoulder of the tire crams right into the cab mount. This happens on both the driver and passenger side.
With 285's I am ok if there is a touch of rub at full lock or if I really start flexing. Since it is primarily on road driving I'm don't expect much flex beyond normal driving.
The tire tested was 285/70/17. I also DO NOT have to have 70/17 but it did look good.
My goal: to see if there is anything else I need to add to the lift and find some specific numbers for wheel and tire sizes to take back to the shop. See if I can find a 2012 DCLB with this set up to mimic.
Thank you for all the info and recommendations so far!!!
