Steering wheel upgrade

Hi Guys/girls, How are you all doing? I've just purchased a 2015 i3 and overall I'm very happy, but the steering wheel is on the thin side for me as I was driving a BMW M Sport 320 which has a steering wheel that is a lot thicker resulting in a good grip. I've been searching for information online, but haven't come across anything besides a "one size fits all" steering wheel cover. So my question is would it be possible to change my steering wheel to the M sport variety or even an i8 steering wheel :?:

Don't know the answer but I, too, would like a thicker/chunkier wheel.

This shop can do what you would like and more. Their work is great. They obviously do custom work also which includes making the wheel have a larger grip-diameter. Leather type and color can also be specified.
