Well the T-case is what is doing the F/R torque split, so that's where i would suspect the issue is, unless perhaps you have an issue with the front axles or something, but i imagine you would hear/know that. Can you the car in the air and just give everything a once over?

I am honestly not sure if there is some ISTA or procedure to "test" the T-case; i imagine there has to be. Might need to do some research on that.

Does it basically seem like you are RWD all the time? Was there a time when it used to launch fine, then all the sudden it did not?
