I picked up a set of M4 front and rear seats. The backs were already painted Yas Marina Blue. I was on the fence about replacing them with carbon fiber backs but the color really looks good, especially with an all black interior.
The rear backs required on to have the bracket swapped as they M4 bracket is different. The bottom has to have a mod done on the back but waiting for it to come back from having that finished.
The fronts only required to swap the computer under the seat. Tried it without swapping the computer and got instant airbag warnings when I connected the battery back. Oh well, I tried the short cut.
All functions in the seats work as normal, except the ///M logo doesn't light up. I'll have to figure out the wiring for that another day. Memory, heat, and all adjustments work as they should in either car.
I'm so happy with the way they feel and they really do look good in my opinion.
