I would not use an aluminum drum in a street transmission. It's main benefit is lighter weight, which equals quicker ETs. That's all. A good steel drum is fine for the street. Even an OE drum IF you aren't racing it.  In general the failure mode of an aluminum drum is the eventual "wearing in" of the steel clutch plates to the flanks of the drum causing them to stick or worst case eventualy cut thoughteh flanks. This happpens to the steel drums as well but at a much slower rate resulting in a once in a life time purchase vs replacment due to wear.
