Initial reports from the spoiler test at Charlotte as mentioned by the drivers is positive, minimal or no impact on handling characteristics that they would have to adapt to. What did change with the increase drag on the straights reducing the speed. The next series of races will be a good indication when the qualifying speeds are compared to last years speeds with wings, especially at the 1.5+ mile tracks.

Did not save, but a Ford aerodynamics engineer mentioned that contrary to common thinking, the wing had minimal impact on the cars becoming airborne.

The May edition of Grassroots Motorsports has a layman's explanation: " Wing It Proven Aero Methods " . Five page article written by a Toyota aerodynamics engineer. The word spoiler is mentioned a few times, but the article is primarily regarding wings, splitters, drag, downforce, aero wake, frontal area, ducts, suspension movement, car design, under car air flow, etc along with maintaining overall balance on the numerous factors.
