Abstract: In previous work we have established a relationship between the shape of the arms in grand-design spiral galaxies and the distribution of mass in their discs. Here we apply this relationship to derive disc mass distributions for five selected galaxies. Our preliminary results indicate that the disc mass--luminosity ratio is low, on average about 3 at the scale radius of the exponential luminosity distribution. No large amounts of dark matter seems to be present in these discs.
