I agree, get the correct M lower steering wheel trim. It won't have that split spoke but wider and solid. It'll fit correctly and you can see where old one sat before by the leather. That wheel uses the M steering wheel lower trim and someone put the Sport split spoke trim there.
I would also go maybe black or shadow on the trim.
