So, I think works wonders as like the first Excessively LOOOOOW Airdam i did, but without the downforce-like symptoms.
I used some 90° bendable vinyl corner edging along the very front horizontal edge of the bumper.
Used up the last of Garden edging in the center, and went bold and overdid it with the Coro in front of the wheels, ironically this worked out waaaayyy better than expected, plus its all flexible still in regards to hitting or scrapping something going forwards. it just folds into itself and springs back!
Still working on the fronts of the wheel for better deflection, but works as-is. will get to it again eventually
