I always loved the look of the OEM sport design rear spoiler, but I didn't want to spend the $1500 plus paint cost on the piece of plastic...I am not a huge fan of the other options (or price) for the 991.2 so I decided to give it a go at my own creation. Always curious as to what the difference was between the 991.1 rear lip spoilers vs the 991.2, I decided to order one myself in Carbon Fiber as I wanted to leave the carbon exposed in the rear. In short, the spoiler for the 991.1 is the correct length, but is bowed slightly more around the curve creating just under a 1/2 inch gap at the center of the spoiler where it attaches to the OEM panel (see pic below). I figured there would be fitment issues, but was not worried as I planned to tackle that one way or another. To attach the carbon spoiler to the factory panel, I utilized rivets (4 total, 2 on each end of the spoiler). I didn't put any rivets in the middle as I didn't want to "pull" the factory panel out of shape and not have it fit the way it was designed. Here are some pics to get started:

I wanted to mimic the look of the sport design, but have it be slightly more aggressive. My plan was to have my body guy "mold" the carbon spoiler into the factory panel and follow the factory lines that curve up in the rear. For the back, I asked him to leave the carbon exposed as I wanted a bit of a different look. I am in the middle of installing the third (center) radiator and while the bumper is off was painting the oem front lip so i figured now would be a good time to do the spoiler. I purchased the paint on my own (my body guy admittedly is not the best at matching) from Glasurit in pure white. Evidently, that is what may be OEM for the car so I figured why not (although twice the price or more of other paints). The code is called Pure White (L9A I believe) and there are 3 different shades so be sure to take a panel or the car with you to match it up. In the end, my match was close but not exact (but close enough for me). Here is how it came out!
Now to installed pics-overall I am really happy with how this project turned out. In the end, I got something different, in carbon (have other small carbon bits to match) and with OEM fitment as its utilizing the stock panel for less than 1/2 the price it would have cost me for the OEM sport design panel plus paint.
Up position (just for install, dont worry-I dont leave it like that...although I may just to ruffle some feathers ) Down showing the profile from the side and how it flow (also cant tell its carbon from this angle) Down 3/4 view showing both the painted areas and the exposed carbon Rear shot showing the exposed carbon-I like how it ties into the black rear diffuser.
Also, in case anyone is wondering-the carbon spoiler was molded into the factory plastic panel utilizing a two part epoxy (similar to "Plastic Weld") but is specific to body shops. This product was also used to fill in the gap between the spoiler and the OEM panel in the back. In the end, its hard as a rock and has very little chance of cracking.
Thank you-I am sure there would be a market for them but not a project I want to take on as the body guy I use is 2.5 hours from me and I would need to secure lots of OEM spoiler panels. Maybe if there is enough interest I will look into making a mold one day.
How is the third radiator install going? Are you draining most of the system or just what comes out of the radiator plugs? Vacuum purge tool for refill? Thanks
Honestly I haven’t started on it as of yet but plan on doing so soon. My plan is to prefill the third radiator as much as possible and only empty what I lose when I make the hose connections to the third radiator. I am going to try to get by without the air tool and see how it goes. Hoping that with a few cycles the air will purge itself.
Having it molded into the rear deck lid was perfect. It looks fantastic. Leaving some CF exposed was a nice cherry on top. Excellent vision for this project.

Thats a solid plan. After you get up and running, could you temp the left and center and right radiators if you have an IR temp gun. Would be interesting to see where things are at. What year is your car?
