Anyone know what type of diff my 2004 coupe manual car has? Reason I ask is that my car was unable to pull away on an incline on the way home yesterday. The left wheel was on leaves and was spinning. The right was doing nothing. I am thinking it is a torsen type diff - if so I should've used the handbrake to transfer torque.

After 11000 miles, I think my RE040s on the rear have seen better days.
