Chaplin - assumeing they are the same size and weight not much from a performance standpoint. Aluminum wheels do dampen vibration better and cool off faster than steel so aluminum wheels tend to have a little less clutch fade. Steel is more stout and will last longer and when it come time to resurface, steel usially needs less cut to clean it up. They both have a steel inserts most times where the pressure plate makes contact. (later style wheels) I know of no truely lightweight steel wheels out there. Oh yes, when a aluminum wheel lets go they make less mess in that explosion proof bellhousing that no one uses.

On the rest, I run both a engine plate and mid plate. In the past I used a turnbuckel setup on BOTH sides of the engine.
