The reason your front end raises is not because of rear downforce it's because of the pressure under the hood. When you go fast enough the air that goes to the radiator has ni where to go so the front end becomes a "kite". I bet you don't have a scoop (facing backwards) on your hood to let the air out....do you? Try that and your kite effect will be gone. I put a 5"x5" hole in my hood right above the radiator compartment and at 120-130mph it feels like 60mph. I have no lift, my responsiveness at 120mph is perfect....considering my old ass suspension. Aerodynamics has alot to do with speeding and the cars ability to "cut" through the wind instead of "plowing" through the wind. Read my 1st post all this is explained. If you add downforce to the rear you MUST add it to the front....vice versa. Aerodynamics is the one thing that can increase top speed and E/Ts without doing engine work.
