Question about custom steering wheels

Question about custom steering wheels  - Ask Car Throttle

Does anyone here own a customized steering wheel (flattened bottom, new upholstery, inserts at the top/bottom)?
I plan on getting one for my next project, and I’m looking for examples/inspiration, and maybe a suggestion for a company (preferably in Germany or Europe, North America is manageable too).
The base of the project will be a BMW E30, so the airbag doesn’t matter.
Also, I’m looking for an OEM-based solution (like the example on the picture), not a “naked” race car wheel.
Thanks in advance!
