We study the balance in dynamical support of 384 galaxies with stellar kinematics out to ≥1.5R_e in the Sydney AAO Multi-object Integral Field (SAMI) Galaxy Survey. We present radial dynamical profiles of the local rotation dominance parameter, V/σ, and local spin, λ_(loc). Although there is a broad...
