It's not standard on the sports seats, but if my memory serves me correctly, you get it with any of the leather seat options. Not just the lounge leather.

 

Still no answers to my first question. Chime in if you know the answer:
According to the configurator, I can get tuscan beige leather with the standard seats on the MC. I am not required to get sport seats. Does anyone know if this is a computer glitch?

 

I think the answer is that nobody knows since almost everybody goes for the sport seats....

I'm liking the Sparcos and Recaros the more I look at them. I think I'd like to get those, delete the rear seats, and put in a roll cage. The big/open back will give my dog more room go claw-in when I'm driving...

 

All of the leather seats have lumbar, and only the leather.
