I went back through Tamai's book,'The Cutting Edge'. The research demonstrated a 70% drag reduction for the solar car's wheel system when the full,swept,fairings were employed,in spite of their frontal area increase.
One of Hucho's examples showed a 53.3% drag increase when wheel systems were added to a low-drag body.
Tamai's work suggests that this penalty could be cut to 16%.That's well worth going after.
