a couple thoughts... link stiffness can be quickly gained with geometry (rather than materials). and, anisotropic materials add a lot of design and build time.
btw, I was in charge of the suspension design of a Formula SAE car in my senior year as well (early 90's) And I was big into composites even before my egr degree. --Yep, you are on a frightful path.

Weight specific strength. I can get the rigidity fine with geometry. The idea started out because I need to make a big triangular rocker arm and I could not find any 9"x9"x0.75" 7075 aluminum plate, and even if I did it would be quite expensive, especially considering how much I would be milling away (pretty much keeping the outline of the triangle with a 3 point star inside). Secondly, I need to learn to mill. Right now my skills are basic at best. I have already played a bit with composites (mostly prepreg though). Third, it allows me to make certain parts in one piece and save on fastener weight and the extra weight around where the fastener goes.
