one thing i think to keep in mind when looking at these things is that the dams in themselves are very unaerodynamic shapes, so they will generate a rather wide "wake",

i suppose they don't need to be the full width of the tire to send the air cleanly around it

so when reverse engineering it's best not to assume "bigger is better"
