  We present next-to-leading order (NLO) electroweak corrections to the
dominant five angular coefficients parametrizing the Drell-Yan process in the
$Z$-boson mass peak range for finite-$p_T$ vector boson production. The results
are presented differentially in the vector boson transverse momentum. The
Lam-Tung violating difference $A_0-A_2$ is examined alongside the coefficients.
A single lepton transverse momentum cut is needed in the case of electroweak
corrections to avoid a double singularity in the photon induced diagrams, and
the dependence on the value of this cut is examined. We compare the electroweak
corrections to the angular coefficients to the NLO QCD corrections, including
the single lepton cut. The size of the single lepton cut is found to affect the
two coefficients $A_0$ and $A_2$ to largest extent. The relative size of the
electroweak corrections to the coefficients is moderate for all single lepton
cut values, and by extrapolation to the inclusive results, is moderate also for
the full dilepton phase space case. However, for the Lam-Tung violation, there
is a significant contribution from the electroweak corrections for low $p_T$ of
the lepton pair.
