We present a kinematic analysis of the globular cluster systems and diffusestellar light of four intermediate luminosity (sub-$L^{\ast}$) early-typegalaxies in the Virgo cluster based on Gemini/GMOS data. Our galaxy sample isfainter ($-23.8<M_K<-22.7$) than most previous studies, nearly doubling thenumber of galaxies in this magnitude range that now have GC kinematics. Thedata for the diffuse light extends to $4R_e$, and the data for the globularclusters reaches 8--$12R_e$. We find that the kinematics in these outer regionsare all different despite the fact that these four galaxies have similarphotometric properties, and are uniformly classified as "fast rotators" fromtheir stellar kinematics within $1R_e$. The globular cluster systems exhibit awide range of kinematic morphology. The rotation axis and amplitude can changebetween the inner and outer regions, including a case of counter-rotation. Thisdifference shows the importance of wide-field kinematic studies, and shows thatstellar and GC kinematics can change significantly as one moves beyond theinner regions of galaxies. Moreover, the kinematics of the globular clustersystems can differ from that of the stars, suggesting that the formation of thetwo populations are also distinct.
