We consider gaugino-mediated SUSY breaking in 5D warped spacetime, where matter is localized on the UV brane, main source of SUSY breaking is on the IR brane and gauge and Higgs superfields propagate in the bulk. We show that warped geometry in gaugino-mediation framework is required from the point of view of SUSY fine-tuning problem. Also, warped spacetime solves the stau LSP problem of gaugino mediation because gravitino becomes the LSP in this model. Finally, we add a small SUSY breaking term on the UV brane. This gives a correlation between tiny FCNC effects from gravity mediation contributions and gravitino mass.
