There are plenty of posts in how to set up a Subaru to limit this tendancy, yours being no different because it's an L and/or a swap.
Thanks. I know how to keep the rear wheel on the ground. I tried that last year and the car was not as fast as i was with the LSD working properly and the exterior wheel lifted. Acceleration corrected but I was not able to apply throttle as soon as before (understeer).
With the DCCD in "medium lock" position, the car is still fast. The only concern is about the potential problem with the DCCD.
A completly locked rear diff COULD be something to try but I heard that it will cause understeer in corner entry! Not better.
