I wasn't quite sure of  what FFR was thinking on these.  Maybe I'll know later.  The bottom line is that at this point in the build, there seems to be plenty of room to do a better enclosure around the front wheels.  I decided to fabricate removable fender wells.  It wasn't that hard.  I simply cut pieces of cardboard to make templates and then trial fit them in the fender well.  I stiffened the structure and screwed the forward edge to the lower spoiler.  The front splitter, spoiler and front edge of this assembly all sandwich together.
