981 S Manual LSD/PTV Retrofit

[HosonAndersson]

Hello,

Is it somebody who knows f it´s possible to retrofit a LSD to a 981 3,4 manual? I´m planning to build a sort of "Clubsport" 981 CS and have found a used object with perfect options, X73, Carbon bucket seats, Sports exhaust and Sport chrono.. But no PTV unfortunately.

I have E-mailed Quaife but they don´t know if the same diff as to the 987.. "We do not have a listing for the 981 Cayman S, however, the QDF12Q may fit as Porsche do not tend to change their diffs that frequently.
I have attached the dimensional drawing for the QDF12Q diff. Please use this to confirm whether it is the same as the standard 981 diff."

Guard Transmission is also offering two different diffs, the classic "LSD" and "Torque Biasing Differentials".. Which is the best for say 50% road and the rest autocross and track use?

So I recived a answer grom Guard Transmission regarding their TBD for the 981 CS. "Thank you for your interest in our products. Because of the new oil pump inside the gearbox we have had to redesign our Cayman LSD. We are close to releasing it, but it will still be about a month." I think this will become a nice solution for those who don´t have PTV on their cars.
