[s-cars] Rotor warp

[Bob Rossato]

Well there are NACA ducts molded into the belly pan for the purpose of
directing air flow to the brakes and the transmission.  Maybe this could be
improved upon by modifying the belly pan by adding in window NACA duct units
like this (http://www.pitstopusa.com/images/BUT7020.jpg) and some 3" hose.
Don't know how much room is directly above these two areas but it might be
worth looking at.  The flow isn't as direct as a bumper mount but I think it
should improve the existing setup.
