Hello, I have been wanting Z4M seats for my 2005 Z4 3.0 for a very long time now. A friend of mine had a Z4M and let me drive it. One of the first thing I loved about the Z4M were the seats. The M seats were so much more supportive and aesthetic and from that day on I wanted to have those seat in my Z4. I have been looking online for quite some time to see any M seats for sale, but I have not been able to find any for sale. I thought of buying Z4M foam bolsters and installing the M bolsters in my standard E85 seat frame and also buying new leather in order to fit the M style bolsters. My main question is, is it possible to fit Z4 M bolsters on the standard Z4 seat frame?
