I thought the Style 163's were essentially the same on CSL's and ZCP/CS packages - the only difference being slightly wider front and different offset on the CSL ?

See - https://bimmertips.com/oem-bmw-e46-m...options-specs/

In fairness, they do say in multiple places that they're just OEM 'style' wheels - they do 19" ones too BTW - https://www.autostyling.com/alloy-wh...em-bmw-wheels/

At that price, I'm sure everyone is aware that they're far from OE...
