Car seems really good so far, very easy to drive and pretty smooth.
No, ceramics don't work very well. They do in the thrust however... for the 3mm balls, I am running carbides and they are flawless. The rust on my rings were not along the diff ball path, so it didn't affect the diff, sanded or not.
