I got SFC fiberglass s281 wing. At the time, it was 135.It was a steal. Took 4 weeks to get it, the finish (gel coating) sucks butt and came with quite a few imperfections, didnt sit flush with the body, 2/4 bolt holes lined up perfectly, 1 barely did, and the other was soooooo off, and lastly, the side of the spoiler dig into my paint and messing it up. Good thing is that i dont have a paint job so i didnt care, and it was $135, what do you expect. LOL. Supposedly,their carbon fiber is better. But i wouldnt spend my money on them for carbon fiber when there are better options out there for about the same price or a little more. Only problem is that i dont know of any other company that makes the carbon fiber s281. But you can make a bad-ass spoiler like mine for literally less than half the price of the fiberglass one..
