Or is tape really that minor? and how do you know where to tape on the front bumper mesh? BTW Please show diagrams or a picture
My suspicion is that whatever difference it may or may not make, the difference is less than your inconsistency between laps regardless of whether you're using tape or not.

Also, if I understand it correctly, the difference it makes is negligible at lower speeds, so unless you're consistently driving at very high speeds, it's unlikely to make much of a difference.

Maybe a rocket scientist can chime in?
