Ther is no need if you do the proper suspension lift. use that money you would have spent on both and get one good suspension lift that has enough clearence for the tires you want to run. I had a BB on mine with 35s and no rubbing. I am putting a BB in my New 2 door w/ 35s should not be a prob. Will post after installed if I rub but I should be ok.
