Quote: have read in the past in some formula 1 sites that anything below 145 or 140 mph aero hasn't much if any effect. in performance.
I can PROVE thats BS... my car was unstable at 133 or so... with the rear wing I picked up a few mph and gained stability... since then now I'm up to 150+... it is about the shape of the rear as Greg pointed out.. but my car being a short hatch back the whole rear of th car was getting negative pressure off the roof line and lifting the car off the ground... I didnt know I was actually spinning my slicks at 133 mph
