many factors, first is your springs. how old are they, how do they sit, next is the tire you are running, many tires the same size are just different enough to rub or not. my 20s just rub on big bumps, that is with an extra 200 or so lbs in the back. width of the rims and tires, 20s come in 7, 7.5, 8, 8.5, 9, and so on. talked to a lot of guys with eibach springs, they say as time goes by, they start to sink until they are broken in. also if they do rub the ls has enough inner fender to shave it or roll it so they dont rub. as far as 22s thats not my style, but if you have a 22x8.0 with about a 30 series you can make them fit, with minimal mods. any bigger they will rub alot when you turn. the black part of the inner fender can easily be cut, bent, or even taken off, but i wouldnt recommend it.
