On the topic of wheels, I think I want to try and get the BBS RG-Rs at the warehouse to fit my 190E.
17x8 is good
32 offset is good
5x114.3 conical seat --> 5x112 conical seat (then I can use more common BMW lug bolts/nuts too)
centerbore is for the BBS PFS centering system so that might just require centering rings
