Of course. The tires primarily rub on the front lower arms when using incorrect backspacing. Front uppers are not affected due to being inside the frame, but it is possible to rub rear uppers if you are running too large of a tire size for the amount of lift on your vehicle. The upper arms are adjustable and would be a more effective way of dialing in your caster angle, however even if you plan on running factory lowers you still would get the same amount of rubbing as the issue actually comes from the tire width and size itself.Thank you for that response. When tires rub control arms, is it only the Lower front or will they rub uppers also. I am asking because your entry kit includes upper not lower. Are upper control arms also adustable so they simply align by pulling in the opposite direction? So the question, with my larger backspace AEV wheel, maybe I should adjust castor with new uppers only?
