I would try plasti dip first. Then consider covering in 3M Di-Noc to give a nice carbon finish.
I've seen this in an M3 and it looked 100% factory. All you need is an inexpensive heat gun from Home depot and some quality xacto type blades that I saw on my last trip to Lowe's.
I plan to cover the backside of my GT3 racing seats with this, as well as ripping out the door carpeting and replacing it with grey alcantara fabric.
