Thanks! I just ordered the same Modern Performance lip for my '21.330IX I agree that it looks the best as not being over aggressive, but has a balance of elegance and sportiness. After all mine is no M3, so looks and performance won't be a match with my 330.
PSM looks utterly ridiculous and does not fit the lines of the rest of the car nor the type of car. The first and last versions fit in perfectly and remain classy.
