Aftermarket wheel hub adapter, quick release advise for track

scruffydog

I'm thinking about upgrading my stock wheel to aftermarket for track. With the research I've done so far, correct me if I'm wrong but I need the following:

Wheel hub adapter + quick release + steering wheel

The trouble I have is finding a great setup for track (the smallest slop/play within the spline, and quick release system)

Hub adapter: (I believe it's Vehicle specific)
This is probably the one I have the most question about. Is this the part that keys into the spline of the OEM wheel and adapts to either a quick release or directly to the aftermarket wheel? Can someone also confirms that this is vehicle specific? If that's the case, which hub do you guys recommend? I'd assume a quality one will have less play than a cheap one since it mates onto the spline, or am I completely wrong on this part and it engages purely by compression of the nut.

The only 2 I found are:
NRG Short Hub Steering Wheel Adapter
Works Bell Rapfix Short Boss/Hub
Are there other brands that makes it? Review?

I saw some dedicated track car just completely skip this hub adapter and straight up weld the quick release to the spline, I prefer to not do that in case I still want to use my stock wheel.

Quick Release: (I believe this is not vehicle specific/ universal)
From talking to some people they recommended me to look into Rennline for quick release. Some say they make one of the best because of the little to no play within the steering wheel and has a tear drop shape fitting so one can quickly slip on without worrying about wrong orientation. That same person also told me this part is where I should not cheap out on. Does anyone know how it compares to NRG? NRG seems to be pretty popular but I wonder how it is for track. Also can someone tell me can I just buy any quick release or do they come with different bolt pattern interface with the aftermarket steering wheel (in my case a Nardi)?

Steering Wheel:
I picked up a Nardi Deep Corn Torino 330mm.

Thank you for any input.
