So here we go...

First up just the two hubs sitting next to each other, the difference is obvious here. CRX on the left, Integra on the right. It's also interesting to note that the CRX bearing has a smaller inner diameter than the Integra one, and weighs about half a pound less.




Now we measure them. I just started with the CRX hub to get the relative difference, so you can see here I zeroed out my gauge:




Here's the Integra hub relative to the CRX one, almost a quarter inch with my deceptively inaccurate measurement. This matches internet findings based on where the wheel sits relative to the rear quarter panel.
