Any pics? You can see it here... I lost control of the car at 135, got sideways and up on 2 wheels... I ended up in the other lane but got it shut down and straight... it scared me big time... I went to work on the Monday and went straight to the wind tunnel and talked to them and they showed me the smoke footage of a P body and the smoke would come off the roof line and miss the hatch/deck lid by 6"-8" so I ended up making a wing... it changed the car like you cant believe 6082949-Mike37.jpg (84 downloads)
