The steel J&M Panhard bar is a little more heavy duty. It's even more resistant to flexing and is equipped with polyurethane bushings, opposed to a standard rubber bushing in the aluminum Panhard bar. Also, the steel version has grease-able fittings to reduce friction and noise.
I would say those are all of the key points. Basically, if you're very rough on your Mustang and/or track it, the Steel is the right version for you.
