After building my Airplane (Velocity), I had some carbon fiber and fiberglass left over so
I built my own trunk lid with the integrated spoiler. You can see a picture of it
in the CSRegistre, enter 2270173 in the search box, It's on the blue coupe.
First I copied the shape of the spoiler in foam and attached it to the end of the
trunk lid. Then, I filled in the gaps and smooth the whole thing out. I used heavy
grade triax fiber glass and epoxy to make a thick mold. After that hardened and
stabilized, I laid up three layers of Bid carbon fiber in the mold and made the new
trunk skin. I then removed the metal skin from the trunk and replaced it with the
new carbon fiber skin. It came out perfect and looks as if the car came that way.
One benefit, no more trunk lid rust around the edges. It also reduced the weight
of the trunk lid by more than half. This summer, I will do the same thing for the
hood. I should loose 50LBS replacing both.
I still have the mold for the trunk, it is very sturdy and one could pull 25 to 30
parts from it with no problems, I'm just too lazy (Retired) it do that right now.
Maybe some one else would like to tackle it?
