Anyone on here ever had problems with MINI's R90s? I've had mine for probably about 9/10months and 3 of the four have weird corroding/staining on the mirrored rim... Two of them have slight kerbing (dont ask!) but the staining is present in areas without kerbing... i feel i should complain to my dealer but they'd probably just say it was due to kerbing - would the complaint hold since this staining is present in non-kerbed areas AND wheels that don't have a scratch on them? How long from buying can i claim faulty product? In the past i've heard people claiming fault issues withR90s...

help / opinion / comments plz ppl...
