Do you gentlemen (and ladies) know what these are? This is the genuine article - not a knock-off.
Installed correctly, they add a measure of high-speed stability, AND set your C4 apart from the rest. Currently bright white, but can be painted any color.
It is way too nice a piece to be sitting n our shop.

Genuine, like new John Greenwood rear wing from his C4 Ground Effects Kit. These are typically seen on 1984 through 1996 ‘Vettes. Painted pure white, with “Greenwood” imprinted on each endplate, wing comes with all original mounting hardware (struts, brackets, etc.), plus full installation instructions.
The photo shows the identical wing (but in black) installed on our #75 IT-E racer. We would prefer NOT to ship. Pick it up in Watkins Glen for $250 cash or best offer. We would like this out of the shop soon. Phone Ed at (585) 865-3969.
