30tooth,
Have you heard of the Tekin Active Link suspension?
Adding an extra linkage to the inner camber mounts has been done before. Turns out the added complexity was not worth the hassle.
It's really hard to build a better mousetrap. There are pics of my car on the 22 4.0 page for anyone that cares to see my ability to evolve a platform. Before the 4.0 came out my 3.99 was a legit .75 seconds a lap faster than a stock 22 3.0.
Who knows though, if 30tooth can get the extra linkage to work that much better, then maybe the next generation of cars will have to have it too.
