Yupp its me again sounding out mad ideas
the basis for this one which was and still might be hydrolic was after I heard something on the tele about the new ferrari having a flap on the front which activates the front splitter
So me being me had a think
then being bored tonight used my highly expensive design tool "paint"
and came up with a few pics and drawings, sorry about the quality and nothing is to scale or real
but here you go have a laugh, O by the way on the line drawing the dotted line is a downward facing flap to catch the wind and the separate bit is a spring to keep it up with a damper to smooth it all out
or it could be a hydrolic ram if needed to be powered, if not then its down to two things the size of the flap to catch the wind or the adjustment on the spring
before:
and after
when up the edges near the front wheel come out an round the edge of the bumper
and about 75% down
