I spoke with a tech at Brey-Krause yesterday who had an 08 R56 in their shop. He indicated that the brackets they have for the Evo seats will fit the stock R56 sliders. He did indicate that one of the bolt holes would have to be very slightly slotted. I asked whether their brackets on the stock sliders would give me the drop in seat height that I am looking for (close to an inch), and he thinks it will.
I will most likely be going this route.... I will post more updates as I have them.
