Nobody answer it so far and I think the question is beyond forum scope.
Members here are are mostly DIY owners who are trying to keep their bellowed rides in good shape without spending a fortune, while your issue is more on racing and tuning side.
From my limited knowledge ASR is using ABS sensors for stabilization. Maybe the sensors are different between the system, but can't imagine why the differential housing would have to be different.
Good luck on your project
