Ebay has them OR similar ones abit more but imo look nicer. I just got a pure carbon fiber one ( similar buuuut mounts onto stock bolt holes for spoiler and must remove oem spoiler even IF it's the tiny aero one like I had ) from ebay and it's beautiful and fitment was perfect..I will have my car soon so I can't post pics yet.
i also got a carboafiber ebrake handle for an r53 for 50$ and a weighted carbonfiber wrapped shiftknob that actually turned out to be awesomely heavy. Just by looking at their quality youd never guess they came off flebay. The spoiler is flawless , it does adjust its angle too ! And i messaged the ebay seller and i got the spoiler for well under 500$ they have a plastic unpainted one for cheaper
