We study the general relativistic periastron advance in spinning black holebinaries on quasi-circular orbits, with spins aligned or anti-aligned with theorbital angular momentum, using numerical-relativity simulations, thepost-Newtonian approximation, and black hole perturbation theory. By imposing asymmetry by exchange of the bodies' labels, we devise an improved version ofthe perturbative result, and use it as the leading term of a new type ofexpansion in powers of the symmetric mass ratio. This allows us to measure, forthe first time, the gravitational self-force effect on the periastron advanceof a non-spinning particle orbiting a Kerr black hole of mass M and spin S =-0.5 M^2, down to separations of order 9M. Comparing the predictions of ourimproved perturbative expansion with the exact results from numericalsimulations of equal-mass and equal-spin binaries, we find a remarkableagreement over a wide range of spins and orbital separations.
