I've purchased quite a bit from Outmotoring, from hood scoops to GP diffusers and coilovers. They are quick to help with questions and the products are great for the money.
Just received my latest order for the R56 Gloss black hood scoop. Easy Install and great fit. Only issue is the gloss finish has major swirl scratches. Not sure if this was a return that got put back on the self or came from factory this way.
I bought these thinking that they might be cheaply made, but I was really surprised. Instead, I read on the box that they were made in Germany; hence, the reason for the high quality. If you buy these wheel center caps, you will not be disappointed. They are very high-quality.
