The South African "Sprintstars", Rostyles or whatever you want to call them were fitted to a lot of 70's South African beetles. Not only special editions.
The most common size is 15x4,5" but they were also available in 15x5,5 and 14" sizes. I'm pretty sure the yellow car pictured with trim rings has 14" wheels.
I think the 14" look stunning with trim rings!
