I hope that some come available soon. The sae report from Ford concering aerodynamics says that if the rake is increased the downforce on the front is increased. It also states that by increasing the rake the uplift on the rear is increaded. I think an approach with the car at higher speeds on a smooth surface would be to lower the entire car 1 or 2 inches, maybe put a little rake in it and possibly a little nose weighting because the car is rear end heavy. Thanks for letting me post my thoughts.
