I had a stock rig on 32’s. They did rub on the control arms. They also hit the fenders a few times. I had plans to lift it, so it was only that way a couple of months. For 32’s I’d do 2” lift. It could be a 2” spacer or springs or a 1” spacer or springs plus a 1” body lift. Or, another possibility is a 1” body lift and a washer on the steering stop. That will probably get you by.
Keep in mind if you add more than 1” spacer or springs you’ll also need shocks.
