True or false cragar 15's in 4 inch bolt pattern?

If you take care of them (regular cleaning and a good coat of wax) they will stay nice for a long time. Get any kind of salt on them, or near them, and you'll have a real mess, real fast. But this is pretty much true for any type of custom wheel, really. Now... the thing I really hated about the last Cragars I had are their junky lug nuts and washers, that only they make. Nobody else makes a lug nut to fit these particular wheels. The nuts and especially the washers will rust, or just get crappy looking, long before the wheels themselves will.
