I have an AWR oil pan on my car and yes there is a possible issue. The lower rear portion of the oil pan is extremely close to contacting the end of subframe where the front of the lower control arm attaches. With AWR front & rear motor mounts and AWR inserts in the sides my oil pan is less half of a cm from touching the subframe. This is not a problem if your engine does not move. Not sure if the AWR mounts change the position of the engine that much, but if you are running stock mounts, it seems to me that you'd be taking a significant risk of allowing the oil pan to wack the crap out of the subframe on hard shifts, etc.
