ufo-lowI really DO need a bigger hammer!

John, I agree with the input so far. Oscillation means you have an "underdamped" condition; your unsprung mass, spring rate, and damping (shocks) are mis-matched. Less spring rate and / or more damping will change the natural frequency.

If you have the opportunity, you might try just removing the rear wing, without changing anything else, see if the issue changes or goes away. Downforce applied behind the rear axle would tend to lift the front end, which might be what is starting the oscillations. That would tell you if the wing is involved or not. Rod.
