On the new generation of recent Subaru cars, there have been great improvements in traction gains as well as stability in handling. Much of these are due to refinements in the multi-link dynamic geometry as well as improved electronic traction control and active management features. However, even with increased performance, there are still many compromises on a standard production car which are aimed for maintaining comfort or noise characteristics. We take these elements and further push the performance traits further.
Cusco Differential Carrier utilizes a box type construction, hand-welded by craftsmen in Japan, and is designed to bridge the main carrier subframe. Not only does it improve driveline response and torque loss, the cross section provides further chassis rigidity, resulting in a more precise suspension pinning points under load, and resisting bowing of the unibody. This carrier has heavy-duty Cusco rubber bushings pre-installed for easy installation.
