(1)It is much better to handle the air over the car than to
add ballast. 

Tom;

That was the solution to my Vettes' handling "issues" also. As
someone already said, those of us with Production cars are
very limited as to what we can do to improve handling. About
the only allowed aero change is ride height and attitude. When
I first started with the car it handled well at 200 mph. As
things got better(faster) It began to move about a bit at
about 215. I tossed out the transverse leaf spring and put
coil-overs on the front. This allowed a whopping 5 inches of
lowering in the front (yes, the stock rubber spoiler DOES
scrape the salt at speed, but not the dirt at EM) After
playing with the rear height, I put it at about the stock
height. Seems that the "wedge" attitude gave me the best
stability, and it is a one-hand drive at 230 now. However, we
all know that every MPH "north" of the best time-slip is
uncharted territory, regardless of what you drive/ride. Guess
that's all part of what makes it fun.........
