Abstract: Glashow and Cohen make the interesting observation that certain propersubgroups of the Lorentz group like HOM2 or SIM2 can explain many resultsof special relativity like time dilation, relativistic velocity addition and amaximal isotropic speed of light. We show here that such SIM2 and HOM2based VSR theories predict an incorrect value for the Thomas precession and aretherefore ruled out by observations. In VSR theories the spin-orbital couplingin atoms turn out to be too large by a factor of 2. The Thomas-BMT equationderived from VSR predicts a precession of electrons and muons in storage ringswhich is too large by a factor of $10^3$. VSR theories are therefore ruled outby observations.
