Have used them on another (non-BMW) car. Inexpensive and fit well, but tend to corrode in markets where salt is used in the winter (they're made in Malaysia).
I've had a set on order for my E92 for over eight months, but my UK supplier finds the Malaysian factory difficult to do business with. As I have an MSport which is fitted with quite good OEM bracing, I won't be that bothered if they never materialise...
