I think it will be hard to find a spoiler painted this color, but by me, it would be far easier to buy any spoiler you find or to use the spoiler you have and just to paint it the colour you need. Recently I painted my car entirely, and the result is awesome. Of course, you can't paint your car entirely, in case you lack experience, but at the same time, you can paint the spoiler any colour you wish. If you want, I can recommend you a site for finding the paint sprayer that would suit you the best. So if you are interested, you can find the site I am talking about by clicking on
