*Adding wheelhouses and wheels to a low drag body can double the Cd.
*Fairings can help 'integrate' the wheels into the body and lower drag,closer to a non-wheeled body.
*Goro Tamai,of MIT's solar race car program performed wheel fairing wind tunnel tests,and asserted that their benefit was so great,even when frontal area was increased by them that you'd want to have them.
*They need to be as large (gentle) as you can make them to mitigate harmful pressure spikes which can trigger separation.
Here are some examples of Cd 0.10 territory cars and their fairings

These on the Template respect the SAE approach/ramp/breakover angles for clearance
