Hello People, Maybe I'm wrong but i think there isn't a Torsen Differential option in game, there are spools & those plustracks on the muscle cars, but these feel like an altered version of the LSD clutch plate kind of differential. There are plenty of Torsen Diffs alternatives on the aftermarket for cars like MX-5, old Benzes & other RWD chassis, it is used as the alternative to Harlex AWD systems which allows for better & more direct power distribution while maintaining a level of freedom on rotation speed of both axles. For me personally I would love to be able to try out different types of differentials ingame before having to spend $$$$ on the wrong diff for my car.
