Is the parking brake cable mandatory for the upgrade to the Wilwood rear brakes for a 2012 Shelby, Or is it a good idea? My OEM cable seems to be to be in great shape.
The issue is that the OEM cables will require modifications to fit the system, while the Wilwood cables will fit out of the box. While you can probably get your factory cable to work, the Wilwood parking brake cable is highly recommended.
