35" tire club

I'm not there yet, but headed that way. Just curious; what is done to the inner tire tub when the trimming is done?? Do you 35" tire-tacos just do away with them, or do y'all modify them somehow??
Second, how much backspacing is being run on the wheels for full lock out steering, and no rub??
I basically have trimming and CMC to do and I'll be set up for 35's, except for the fact that I have the Rancho UCA. I do believe that UCA should work, as it does not stick out like factory UCA'S, and looks no different than the FOX, except mayne for true uni-ball on Fox...
Any helpful hints, thoughts, ideas, greatly appreciated.. Thanks in advance my fellow Brothers of the Taco!!!!!
