You don't need to do a body lift to fit 31"/32" tyres. Just trim the fat out of the rear of the front arches and bobs your uncle. A 2" Suspension lift might be more what you need and easier to do as well. My Dti had 265/75 r16's (32") on no problem with just a 2" lift (see the Dti link in my signature)
