There is plenty of room for overfilling in both N20 and N55 engines. So far so good over here and I run 245 square RS4 tires. Definitely not a bullet proof solution but better than nothing. Baffled pan + overfull would be enough on a street car running semi slicks. Things get dicey when adding camber adjustments, sway bars, etc.
