Chris, I said 6 of those wheels in a 6WD drop, in 2006. We had trouble turning. I don't know if there is any video of the Arizona practice rounds around, but we bounced around a bit.

Solution: the front wheels, which were the primary off-ground wheels (6WD drop drives rock a bit, but can be weighted so one set or the other is mainly on the ground), were replaced with 6" Skyways. No more problems. In 2005 we used 6" Skyways on the corners; in 2007 we broke quite a few AM hubs on our rear wheels, but not so many on the front wheels. (We also caught a hub that had partially failed. Mark Koors happened to be the FTA at the event, so he got a wheel in the process of failing for analysis.) 2008 saw the revised AM 6" wheels on the corners.
