I saw [link=http://rcglowplugs.blogspot.com/2007/12/xray-releases-official-xb8-mud-scraper.html]XRAY released a set of mud scrapers[/link] that go inside the inner wheels. They are supposed to make the XB8 jump better since mud won't be able to accumulate inside of the wheels. Is anyone using these? If so, do they make a big difference?

I have a friend that uses them on his associated RC8. They are only needed if your track is really moist. Have to be careful things can get wedged between the rim and the scraper. I have seen that one happen in a race.
