I had an ALL aluminum 6x15" discbrake wheel a couple years ago.....stamped "LM" in the center.....meaning leichtweight. This and several other wheels I`ve had are not on the list.......for example, there were 3 different 904 wheel sizes.

It seems this topic would better have been titled, "Aluminum Rim Wheels" Porsche supplied the aluminum rim, steel center wheels for their competition cars. These were almost all 4 1/2 J 15 wheels because it wasn't unitil the mid 1960s that Jim Hall discovered that wider rims had an advantage. Charley Gibson, national FM champion went on record that wider tires hurt lap times more down the straight than they helped in the corners. Jim Hall wasn't seeking a cornering advantage; he was seeking a way to get the power of his Chapparal down to the ground.
There were, of course all manner of "mag" wheels, some of which were actually magnesium, most of which were aluminum and offered no weight advantage. It seems to me that the first aluminum wheel that actually offered a performance advantage was the forged, rather than cast, Fuchs wheel which appeared in 4 1/2 width on some 1967 911s.
A few years go Stoddard announced that they were going to reproduce the 356 Porsche steel/ aluminum rim wheel but so far nothing has come of that.
Harry Witham in Oz will make them for you.
