Those were definitely a switch.
There were 2 options available for 1983-1985.5 and that was Fuchs (high end aluminum) found on the 911 or Cookie Cutters (Steel). In 1986 the Phone Dial (Aluminum) was added as a choice, and Fuchs and Cookie Cutters were dropped by 1987. The idea was to put the 944 more into it's 928 roots. The dish wheels were added in 1989 as were the C2 Type 90's. Ironically the 911, 928 and 944 ALL had C2 Type 90 wheels by 1990.
