sternes are the centers..... search google image for "felgensterne"
The time and money that went into these are unlike most "fully chromed" multi piece wheels...as every "window" was polished after every plating bath. Its not necessarily the plating process that costs money, its the MAN HOURS of polishing put into each sterne. Most people just polish the sterne face. These are polished in the back, front, inside, EVERYWHERE.
Hope that helps explain things
Snce you've posted these, I stop through and gaze at the chrome plated sex,lol.
It is what it is!
