There are some similar designs made by BBS:
- original BBS CH (MOTORSPORT): different sizes and bolt patterns (VAG 8x18 ET50)
- new BBS CH-R: dito
- cheaper BBS CO: without 'Motorsport'
VAG 5x112 only:
- BBS VZ033 (Votex/driver gear): 8x18 ET44
- VW Pescara/Rockingham (ED30): 7.5x18 ET51
- Audi A3 S-Line '14-spoke-design': 7.5x18 ET54
- Audi A4/A6 S-Line '14-spoke-design': 8x18 ET43
So the Ebay items seem to be the Audi A4 (8E)/ A6 (4F) ones or the offset is ET44
and they are VZ033. In no way they are original BBS CH.
