Rothsport makes one of the best steering wheel quick release I have found.

The Rothsport steering wheel hub is very close to the Porsche unit.
The taper removes the slop that splined hubs have and also make it very easy and quick to put on with the correct clocking. IMHO this style quick release is vastly superior to the splined style.
