Hello TMC, I just finished mounting my Amazon CF rear deck lid spoiler and I thought I would make a quick post about my experience. A few weeks ago I purchased this guy (full disclosure, I didn't actually spend any money on it, I buy a lot of stuff from Amazon for my company and get mad points) expecting it to be awful and get sent back. Took a week to arrive, came in a stupidly large exterior box (thing was 4ft by 6ft by 8inches or so) unboxed it and found that the inner box was damaged, I'm guessing at the Amazon warehouse as the outer box was fine. I inspected the spoiler and found a small chip in the clear coat corresponding to the area of damage on the box, it probably wouldn't be noticeable, but I'm a pretty OCD guy so that wasn't going to cut it. Packed it back up, had Amazon send UPS out to grab it and they cross shipped me another. They shipped ground from Florida so each time it took a week or so, but the second arrived last weekend and this time it only came in the inner box(!?!) AND to add insult to injury this box had obviously been opened previously as the tape was cut and re-taped, however after inspecting the 2nd unit it was flawless.
Did a dry fit on the 3 and... well... now I know why the box was open, someone must have purchased it, dry fit it, realized the fitment sucked and sent it back. Given I didn't actually pay anything for it, I decided why not try and make it fit? The spoiler itself is ABS or some similar plastic mold that is overlaid with CF, after numerous dry fittings I identified where the inner structure was too close to the edges of the spoiler causing a 2-3mm gap on the last 6inches or so of each side. Queue the dremel, I did my best to remove as much excess material from the interior as I could, and sanded the crap out of plastic mold. When I purchased it I had assumed it would come with knock off mounting tape, and true to form, even though the amazon listing said "genuine 3M mounting tape" it was not, just some random red backed tape, so I applied my own 3M tape. Admittedly this took me a few attempts, the tape itself is probably 2mm thick so it would push the spoiler off the deck lid just a bit. 3 tries later I realized that I should try to adhere the spoiler to the "underside" of the trunk lid, the inner mold is essentially a "<" shape, so I only put tape on the lower leg of the "<." I made sure to clean the surface and use some adhesion promoter before applying the tape. Did the same with the trunk lid, pulled the tape backing and went a little overboard with the painters tape. I let it sit for 6-8hrs in the sun before removing the painters tape and here is the end result.
Look at that edge fitment! Better than stock! I am pretty thrilled with the results as I read numerous reports of the OEM spoiler not fitting great especially on the ends. The photos make it look like there are weird lines or blemishes on the spoiler, its actually a reflection of my house siding, there isn't a single imperfection in the gloss or carbon fiber.
Now lets see if it stays in place. I've got a few hundred miles or driving coming up next week, ideally it will still be attached when I return! Only time will tell if the clear will crack or discolor, but for today, I think it looks pretty darn good.
