  Using the Yukawa couplings of the minimal supersymmetric SU(5) model, the
rates for $\mu \to e\gamma$, $\mu \to e$ conversion and $\tau \to \mu \gamma$
are computed. For a selectron mass of 100 GeV, and without exploring the full
parameter space, we find rates which are one order of magnitude beneath present
experimental bounds. It is argued that these relatively large rates have a wide
applicability, so that lepton flavor violating signals provide a more general
test of supersymmetric unification than can be obtained from either proton
decay or neutrino masses.
