The Weibel frame for Weibel-type CFI in unmagnetized relativistic pair shocks moves subrelativistically relative to the background plasma with velocity scaling as ξ_b and is slightly slower than the plasma relative to the shock front.

abstract
We develop a comprehensive theoretical model of relativistic collisionless pair shocks mediated by the current filamentation instability. We notably characterize the noninertial frame in which this instability is of a mostly magnetic nature, and describe at a microscopic level the deceleration and heating of the incoming background plasma through its collisionless interaction with the electromagnetic turbulence. Our model compares well to large-scale 2D3V PIC simulations, and provides an important touchstone for the phenomenology of such plasma systems.
