So I tried putting on my momo hub, then quickrelease, then sparco wheel.
It just was too long, so........
This is what the momo hub looked like before:
That raised part is for crash protection so your chest doesn't get pierced by the steering shaft. In a caged, harnessed car, this is less of a big deal. So...
Cut of the tabs with an angle grinder and thew it in the mill:
A shot of the completed facing:
Then I drilled and tapped 6 holes and test fit the wheel onto the hub (the bolt pattern of the wheel is the same as the quick release, and it came out perfect)
The wheel is installed on my car right now, but no pics of that...
