wrong offset on my wheels

Well stock would be the pressed steel units as opposed to aftermarket tubular A-arms .
Was the car running driving when you purchased it?Just wondering if this has been going on from the time you aquired the car or if something was changed and then the noise started.That would narrow down your search.Like I said easiest thing would be to pull a wheel and see for yourself exactly what is rubbing.Look for any shiney metal or powdered metal flakes to lead you to the source.First look to see if the tires are rubbing anywhere.
