I saw in the last accessories catalog that I picked up from the dealer that the last Z3's had a part number for the M3 steering wheel. Doesn't help the M coupe or roadster crowd, but I wonder if this wheel would make your life any easier? I kind of wish that when they did the restyle that they added some of those changes, i.e. a steering column that would accept the E46 M3 wheel, to our cars.
