  We apply a recent and simple technique which speeds up the calculation of
localized collisions in holography to study more realistic models of heavy ion
collisions via the gauge/gravity duality. The initial data takes into account
the lumpy nuclear structure of real heavy ions and the projectiles' aspect
ratio mimics the Lorentz contraction of nuclei during RHIC collisions. At the
hydrodynamization time of the central region of the quark gluon plasma
developed during the collision, we find that most of the vorticity three
vector's absolute value is deposited far away from the hydrodynamized part of
the plasma. Only the relativistic corrections to the thermal vorticity in the
hydrodynamized region are non-negligible. We compare the transverse flow after
the collision determined in this work with previous results, without granular
initial conditions and determine the proper energy density and fluid velocity
in a hydrodynamized subregion of the plasma.
