Lots of good information here. If I could go wide five, I would look into the Vintage wheels, but wide fives won't fit a 911 suspension. That leaves the beautiful Technomagnesio wheels out also.
Coddington/HRRB/Alloy Replicas (as Carey recommends) is being looked into also.
BANZAI's Fuch wheels are gorgeous, but are 15". With brand news on my current wheels, I'll try to stay with 16".
The 911 set up in Henry's IM6s take a very specific offset and width front and rear, as there isn't all that much room in there for wheels. Porsche 993 or 964 cup wheels will fit, but they look too modern.
Life is so confusing some days...LOL
