On the original 2005 Aeromax, anyone know the source of the wheels or were they one offs?
They won't fit a Ferrari Richard.
Don't know the answer to your question - always wondered about the similarity of the 15-spoke 3 piece split rim to the Alpina wheels fitted to B7s many years back. Something similar in the curve profile between the spokes at the rim. Plenty of differences though... Hex centre cap on the Aeromax prototype wheel, less rim offset etc (though easy to change on a 3 piece wheel)
