You dont find many spare wheels like this anymore. All the Porsche enthusiasts have been hoarding this stuff for years. The Porsche Carrera 2 used a special 4 cam performance engine. It seems the Porsche Factory created special wheels for this model with thicker wheel centers to match. It even has the correct original parts sticker and stampings that corresponds to the Porsche Factory Service Bulletin.
This is a 1960 Porsche 356B Super 90 coupe. It currently has a non matching engine which is a 1600 super engine. Matching engine unknown at this time. It appears to have minimal rust. The floor pans are solid. This is a major restoration candidate but worth doing.
