Laurence, check EBay item numbers 111592541415 and 401314401692 as just two examples, other colours are available. As the brake calipers are set back from the hub face these can be fitted without any difficulty. They are not solid covers but have the drilled disc appearance and will certainly reduce the amount of brake dust reaching the alloys hence cleaning will be less frequent and easier overall. They come in pairs so you’ll naturally need two sets, cheap enough too 🙂
