        Incorrect parts

        When I received my Clinched Flares Ducktail Rear Spoiler, it was slightly damaged and I did not get the correct screws for installation as well as not enough.

        5 2015 GT - 5ohcubano Installation Time: Shop Install Installation Cost: $250-$500

        Absolutely in love with it!!!

        Product came well packaged, no damage at all. Comes with all the hardware you need to install it. I had the option of just adhesive mounting it, but I prefer the look of the bolts and had it drilled in. Had it painted black and shop installed. Took about two days, full day for paint to dry then installation was about 3 hours for a total of $375. Would absolutely recommend this spoiler!

        5 2015 GT - WheelMan Installation Time: Afternoon

        Overall, very satisfied!

        Being that there really is only one issue I have with this spoiler, I'm going to get it out of the way first. The price is very high, in my opinion. I contemplated for much longer than I have on most anything else simply because of the price. It's an injection molded ABS part, with some basic stainless hardware. Definitely not a $400 in my opinion. However, having said that, the style and fit of this wing are exceptional. I am a huge fan of form fitting spoilers (or duck tails as they're called). This one adds that rear body shape that mimics the old 67' Shelby's, which is what I was after. The spoiler came pre trimmed, and pretty accurately I must add. I only had to do minor trimming in order to get the exact fit I wanted between the spoiler and the trunk lid. Once painted, this thing really adds to the S550, if this is the look you're after. There are other "duck tail" spoilers out there, but this is definitely the one, in my opinion.

        Had to return

        While I loved the look of the spoiler before I had purchased, when I was getting ready to install it doesn't sit flush. The endings don't sit how I would like and show quite size gaps between the spoiler and trunk. Had to return.

      Is there any reason this product won't fit on convertible models besides the fact that it covers the third brake light?

      • The decklid/trunk for the 15-19 convertible models has a slightly different design, which is why this spoiler would not have proper fitment.

      • The spoiler arrives in a gray color, it does not arrive in black.
