I mentioned this in another thread, but
Torsen only makes four models of differentials: T-1, T-2, T-2R (Racemaster), and T-3, and they are found in a wide variety of cars. The T-2 is found in the IS, LFA, Imprezza WRX STi, Genesis Coupe, the Mustang Boss 302, etc., and will be in the 86/BRZ/FR-S.
And for what it's worth: JTEKT Torsen is part of the Toyota Group.
