As part of the SAGES Legacy Unifying Globulars and Galaxies Survey (SLUGGS), we have obtained large scale (out to 2.6 effective radii), spatially resolved stellar kinematic maps for over 25 early-type galaxies. I will present these kinematic maps, kinemetry fits and variations in the angular momentum as a function of galactocentric radius. Changes in the dynamical support (rotation versus pressure) as a function of radius in multiple systems emphasize the need to survey the faint outskirts in order to obtain a complete picture. These results are used to infer the individual assembly history of the galaxies in our sample.
