Hi All. I'm getting my 1st A4 in about a week. Not a fan of the premium plus wheels it comes with and hope to replace them with the 18" Cascara rims in the A4 Brochure. I got a quote from the parts dept and seem way too pricey. Does anyone have recommendations on where else I might be able to get them? I'm looking for that wheel or something similar to what the 5 spoke 18" Mercedes AMG wheels look like. I know there are aftermarket places to buy from, but not sure which are reputable. Any advice would be appreciated. I've also been reading up on coating the rims to may it easier to get brake dust off. Heard of Rejex, Sonax, and Opticoat. Is one a lot better than the other?

Thanks,

Frank
