The Ichiba V2 spacers are the ones that come with the built in studs.
wow Nebz, you have had your problems. I think for you, it would be best to take your wheel set up with your ride to a good wheel shop and let them see what you really need to run these wheels safely.I ended up not needing a spacer. The wheel is 74.1 so I bought the ring 74.1 to 66.1. The inside diameter works fine. It looks like the outer diameter is measured by the lip or profile that flushes up to the hub, the outer lip edge would be really close but when it tapers down it leaves to much space from the wheel to the ring. I'm going to try and find a good wheel shop and see if they have rings.
