"Cup design92, Forged aluminium aka Cup1" - I thought the Cup Ones were cast alloy? Only forged Porsche wheels I can think of the the time are the 928/944Turbo SE wheels, which look a little like D90s.

If the Cup design 92 were forged, they would be much lighter IMO.

Indeed, the forged wheels I have had and seen had very thin spoke profiles. I would have thought, from the design and weight of the Cup Ones, that they are all cast, even the mag. RS wheels. Would like to think they were forged; an added bonus for me
