No you wouldnt need them for a 18". I'm not even positive if you really need them if your running bigger rims. They push your rims out and you gotta role the inside lip of your fender. Before i put them on i could lay out and even turn a little. After i put them on when going down i would rub on one side and i didnt drag frame anymore at high speeds anyways. It was a mistake to buy them anyways cause my upper shock mount in the front was hitting something else i cant remember keeping me from laying out, it would've just took 5 minutes to grind it down and lay out. I was just running some 17" cadilac rims. Sell them you got no need for them.
