Yes my rears make the same noise!! It's like a rattling / squeaking noise.
I only hear it at low speeds, which is odd! I'm glad I'm not alone with the noise!
Yes i'm happy too that i'm not the only one but strange from a brand like Kw 
Maybe something wrong 
maybe we must write a mail to kw from all of us who have KW V1 
Speedline decided they liked the photos I took the other night that much they wanted to use them for marketing etc. So in return I now have a slick corporate fleece from them. 
Pretty chuffed to have my pictures recognised by a big company and they love the MINI too!
