G290 Steering wheel

Can someone help me with this steering wheel please. What are the bumpers for around the inside of the wheel?

Could you rephrase your question?

I honestly have no idea what you mean with ‘bumpers for around the inside of the wheel’. The holding clamps?

Maybe post a picture and mark the spot you are uncertain about?

Are you maybe talking about the steel paddles? You can use them for easily shifting up and down without needing a gear stick.
