    Too many variables; depends on wing profile, width, area, height of mounting plane, whether or not if obstructed and how much obstruction, etc.

    Call the wing manufacturer and ask them, and if unknown, I would start with a neutral to 2 degree angle of attack (aoa) and work from there. The wings aoa should produce downward pressure on the vehicle.

    Also, the spill plates will have a large affect on hi-speed stability.

    I run high 6's low 7's with my altered. I set my rear wing at 2 deg. Its not a big wing though. not sure of exact size right now, maybe 30"X 16"???? I just have a "Hammer Head" nose on it, so not sure what to do there. The car moves around a little until 660 mark or so, then you can feel the wing start working and car gets good and soild.

    Just like (fuel cars) said above...he is 100% correct
    are fiat ran 5.80's in the 1/4 and 3.90's in the 1/8 , with the lencodrive and hemi.
    One wing (a cheaper one ) we had to run 6 to 8 degrees
    the wing : Jd2chassis.com built we only had to run 1 degree
    thanks
