Customized "Barocks" 😃 If you gonna make them, make also stock ones. They are 14" and 15". About AMG Penta, they're in few different sizes and width 🙂 Cheaper rims which looks like AMG Penta are Ronal R9 (available as 15" and 16" can't remember data about width ;/)
If anybody wants info and pics of typical rims for Mercedes (stock, AMG, Carlsson, Brabus, Lorinser etc) PM me 😉
