Sean, there's no such thing as too much oversteer in an AWD for the street... believe me.

If you were fine tuning your car for a strictly track setup then its another story, but this is a street car. You want it to be a fun ride, and there's nothing finer than being able to kick out the rear end at will through turns. Its not like a big torque RWD, you still retain full control of the car.

I still say you should do 350/350 or something like that... but thats just my silly opinion. Im sure you'd wanna listen to a professional instead.
