We consider SUSY GUT models of flavour capable of explaining the flavour structure of quarks and leptons, via the spontaneous breaking of a non-Abelian family symmetry. We focus on the consequences of such models for the SUSY-flavour structure, i.e. for the soft SUSY breaking terms. We highlight generic features of models with real triplet representations and discuss a new class of models based on $SO(3)$ or $A_4$ family symmetry, broken by the vacuum expectation values of four “flavon” fields pointing in postulated specific directions in flavour space. The class of models allows for an excellent fit to the present quark and charged lepton data and leads to interesting predictions for the neutrino sector as well as for the SUSY-flavour structure.
