Hey 100% i agree with every thing you said to the t. My ofna would blow back also just like you said but i took off the "high downforce wing"which was made for tracks i put in a tri level wing and removed two levels because the wing dosent need downforce at least for me but as you say with the ofna high downfoce wing at 65 mph it blows back ,we call it dancing which is bad for racing really bad! As for the buggy's body i use industrial velcro all around and i have vented fully the body for positive air flow and cooling .The guy i raced took the body off too....... spinnnn outt it also needs weight!!!
