"The center of mass behind the center of gravity."
Amen but not too far behind CG. Your statement above
goes to the heart of my comment on CG intersect with
CA. It may have been better for me to reference center
of mass rather than centroid axis. The two are so very
similar, I tend to use them interchangably. I am not
a big fan of adding weight unless the rules forbid
aero devices. Weight is such a big penalty, even at
Bonneville. Simple, yet effective aero devices offer
downforce or generate negative lift in areas you
require it and at very low drag. The trick is feeding
these devices air properly.
