I'm looking for a set of rims and drag slicks that will bolt up to a c-5 without any modifications? I would prefer not to use drag radials although I think this maybe my only option if I have to use a 17 or 18 inch rim. It seems that all the drag slicks on jegs are 15 and some 16 inch. I don't think a "drag radial" would be aggressive enough for my pro chared c-5 unless someone knows of a very aggressive one. thanks
