Rear Diffuser
I'm not sure what the weight loss is with the carbon fiber hood, but if I had to guess I would say it was about 35-40 lbs. I did the install myself with my dad and the CF hood was significantly lighter. CF could carry by myself whereas the OEM was very heavy (two people needed for sure). I did not paint the CF hood. I really like the look of it and it goes well against my millennium silver SC on black leather. Great combo. Can you send a picture of your CF trunk lid spoiler? Was thinking about doing it, but haven't decided if the cost is worth it. Thanks!
I just weighed the OEM AL hood and it was 30.8 lbs while the CF I think is 15 lbs. The steel OEM trunk is 42 lbs and the CF trunk lid is 14 lbs. I'll post picture of the CF trunk lid soon with the spoiler, 3rd brake light and tail light extensions. I did not paint the CF but added silver pinstrips to match the black pin stripes I put on the rest of the car. I left the spoiler and 3rd brake light in millenium silver too. I think it looks great.
That was a real pain. I had some body repairs done a few years ago so I don't the spoiler was from the OEM install but there was a LOT of 3M molding tape (the heavy duty stuff with the red backing) on the bottom of the spoiler. First I removed the two nuts and twisted two clips. Then with a wide molding remover I had to go all the way around and break through the tape. I put masking tape around the edges to protect the paint. You can tell when you break through. The ends and center is attached via a plastic socket that is inserted into the trunk lid. The spoiler has ball headed pins that go into these sockets. You could just pull really hard until the pins come out but you may dent the trunk.mSo I simply broke the sockets from underneath and then ordered new one for the reinstall. I used less tape when I reinstalled ...

sorry to revive this thread thats been dead since before I bought my SC, but I just found it and did a little searching and then I found this:

In that thread, someone finds a replica version of the diffuser which is still listed on ebay:
https://www.ebay.com/itm/201504604360
Seller: autumwish (incase the listing goes away)
I checked and they share the same measurements. I'm going to give it a try for $40.
Just thought I would share incase anyone else sees this thread.
Also, the original spoiler and the original seller are still available from EuroBoutique for $240 shipped:
