Forget about the G29 steering wheel.
The real deal is building your own wheel at home. On the internet there’s tons of material and even Facebook groups to learn how to make a homemade wheel to use in your simulator. For comparison, a G29 as of today costs almost 3000 reais. It’s much more satisfying to make your own.
Take a look at this customization with a VW steering wheel:

I recommend doing it with a Peugeot 208 steering wheel, because they’re comfortable, good‑looking, and quite small.
