The Cusco RS front 1.5-way limited-slip differential is built for CT9A Evo 8–9 applications that use ACD and do not have a viscous coupling. As a 1.5W front unit it moderates lock during cornering while still providing on-throttle traction benefits. The RS configuration is tuned to work with the CT9A ACD system to maintain predictable front-end behavior under varied driving loads.
