Well I got the new trunk bolted to the car today.
This whole project started with the idea of putting a GTO wing on my factory steel trunk. But, since the holes don't line up I would have to drill out new holes and fill the old ones. I also wanted to fill the factory third brake light hole and fill in the little location holes for the emblems and badges. After welding the holes shut and the bodywork and primer, I would have been painting the whole trunk anyways.
So that got me thinking; what if I could find a carbon fiber one for cheap enough...they don't have any holes drilled for the wings and no holes for the emblems/badges. The only thing I would have to fill is the third brake light hole.


I ended up getting a sweet deal on a Seibon carbon fiber trunk.
Well when I got it home and bolted it to the car, I wasn't that impressed with the fitment. The gaps between the trunk and the quarter panels was unacceptable for me and the gaps were uneven all the way around. So I set out to fix that...Heres my story:
This first picture shows the fitment when I first got it. The gaps needed to be close up by roughly 1/8" I know it doesn't sound like much but it was definitely noticable

 

These next few photos show where I filled the third brake light hole and had to add some material to the underside to fill the gaps. I used fiberglass tape and vinyl ester resin.

 

And then after adding material to the top side and doing the necessary bodywork, I primed it, block sanded it, primed it again, and blocked it out for the last time. After drilling the holes and test fitting the GTO wing it was ready for paint.

And finally, the assembled photos:

 

looks nice, I have never seen a trunk lid without the 3rd brake light before. clean look. what about legal requirements for safety? don't you need 3 lights in IN?

 

Looks just like mine except in CF. Same color and everything.

The GTO wing has integrated LED 3rd brake light. I can't say that he hooked it up, but it is there.

 

The GTO wing brake light is wired in

 

Thanks, I have always thought the trunk was too crowded with the third brake light and the mazda emblem and Mazda symbol and the "RX-8".
