The cables are a stainless steel direct fit replacement for the OEM gear cables. The OEM units are a known problem and a source of impending breakdown. When (not if) they do snap, you will be very lucky if you are not stranded on whatever road or motorway it happens on.
They are also not man enough (in any way shape or form) to be used in mid-engine applications, that many people are using the G50 or other Porsche gearboxes for.
