will they fit the razor 360 bike?

Yes, they fit the 360. So far (a few weeks of use) they've held up fine.

You don't think approximately $36 (including shipping) for ripster wheels is too much when the ripster ripstik only costs $2 more?

You are right, but keep in mind, Ripsters will not be that cheap for too much longer longer.

Can they be used for Razor Crazy Cart rear wheels?

I don't know for sure. I would contact Razor and ask someone in customer service if the wheels are interchangeable. I had no problem changing the wheels on the rip stick caster board with these or the rear wheels on the "Powerwing" toy by razor (same size).
