For sale is a used OEM M steering wheel trim that came with all F generation M cars (at least in the US). It's far nicer than the stock plastic M sport trim. On this piece, the silver trim is aluminum, and the surrounding black trim is (I believe) leather. Feels very solid in the hand.
Comes with everything you need to do the retrofit: trim, back "plate", and foam dampening element for vibration motor (if you have lane departure warning). The piece is in excellent condition, no major signs of wear, only damaged part is one out of the three clips (red arrow pointing at good clip, broken one is circled) in the top air bag area but it has zero impact on how the piece holds together.
