We extend the computational framework of \citeBuchel:2023fst to analysis of shear and bulk viscosities in generic strongly coupled holographic Gauss-Bonnet gauge theories. The finite Gauss-Bonnet coupling constant encodes holographic plasma with non-equal central charges c≠ a at the ultraviolet fixed point. In a simple model we discuss transport coefficients within the causality window -\frac12≤ (c-a)/(c)≤ \frac 12 of the theory.
