Wheels are porsche Sport-Classic II, made by BBS.
Size is 18x7,5 and 18x9. Quite rare in this size as it was an option on Boxsters only. The 996 got the even wider 8 and 10Jx18 as an option only as well. I really wanted the smallest 18" in this wheel there was. Took a while, but I am very pleased with the results

When there's an engine in it again, I will post some pics of the car outside with all 4 wheels on them
