I've been running steel Bassett (think dirt track racing) beadlocks on my YJ for a few months. Aside from a couple of light scratches and a small ding in the lock ring they are good. I got them new for $110 each and that included shipping. There are some pictures in the Wrangler, YJ, TJ thread area. Might be limited on a good offset for the Commanders though. Also the 15" limit might not clear the caliper.
Here is the link. Wheels are at the bottom.
