I will discuss the A4 Randall-Sundrum model, aimed at a simultaneous explanation of quark and lepton masses and mixings. After introducing the model setup, I discuss the LO and NLO results for fermion masses and the quark and neutrino mixing.

In particular, I will demonstrate the way realistic CKM and PMNS matrices can be accommodated with natural O(1) parameters, considering also the recent measurements of theta(13) by RENO and DAYA Bay. I then discuss the phenomenology of RS-A4 and the most significant constraints coming from EWPM and rare processes in both the quark and lepton sectors. Special attention will be given to the calculation of 1-loop contributions to dipole operators relevant for the nEDM.

Finally, I discuss Tree level contributions to cLFV (mu-->e,3e) and B_{s,d}-->mu+mu- mediated by anomalous Z couplings, in light of the wealth of current day and future experiments addressing these processes. It is shown that cLFV together with EWPM, impose the strongest constraints on the Kaluza-Klein scale and the model parameters.
