Tahko GT-21 is a good first step GD takes, but I think we all hope to see more partnerships with the racing industries like Fanatec partner with BMW and Bentley to develop their real GT3 cars wheel, maybe a Mclaren Simucube gt3 wheel? 
I do think with this kind of collaboration, will let more people know about this great product!
I would think there’s more affordable ways to promote good products. I mean I don’t think Granite devices could not do it, but at the same time car manufacturers are probably not doing that collaboration with Fanatek for free either.
