What kind of rims are these?

BWA Sportstars. 13x6 wrapped in 205/60/R13 Stinger Radials (need spacers in front due to larger 1g Integra brake calipers). I purchased them from a BMW 2002 wwner and found out these were popular on old fiat, VW, and Alfa Romeos of the 70s.

Interesting.  If I recall correctly, most vintage Alfa Romeo/Maserati/Fiat wheels were made with 4x98mm bolt patterns.  Are the BWA Sportstars different?  I've looked into Alfa/Maserati/Fiat rims on these cars before and it looked like you needed either 'wobbly bolts' or wheel adapters to run a 4x98 on a 4x100.  Just curious.  Always on the look out for unique wheel options for these cars.
