Hi, I ordered these parts a week ago from Germany.
They have arrived today. (so quick!)
In my case, It seems that the top of bolt (connect "Mounting Ring" to "Strut Bar" ) interferes against "Microfilter Cover" a little.
In order to make cleaner install I had to cut the top bolt - this modification make the whole install more aesthetically looking.
In general - this is great low cost modification to my car.
Thank you for posting!
