I have been searching around for some retro style wheels for my refurbished Z3 2.8 (1998) which I have tried to continue with the Z3's original retro (50's/60's) styling (which is what attracted me into Z3 ownership in the first place) ...personally, I am not into the seemingly popular 'low stance street racing' styled Z3's (for me, the Z4 is better styled for that), but each to their own... I currently have M3 wheels which are not in keeping with my overall style in my POV & the closest I have seen to what I like is the old style BBS wheels which seem not readily available apart from copy wheels from China (which I am still thinking about). I do not like the OEM wheels & most aftermarket wheels are too 'street racer style' for my taste. Although many people dislike wire wheels on cars produced long after their demise, I think they can work well with the Z3 (especially a dark colour like my Violet Red with chrome touches around the car (front grill, handles, lights etc)). I am not a BMW purist and am not trying to keep my Z3 stock, rather enhance it in terms of performance & style as per my 'vision': "a classic styled roadster that is a practical everyday drive and can still be pushed occasionally without feeling guilty about it!" ... I have contacted a few wire wheels companies and none can supply (despite on line claims that they can (eg MWS)) so I am now contacting what is about the last hope, Dayton Wire Wheels (USA) ... probably go for direct bolt on rather than splines... they cost a small fortune, so I have not made the final decision yet ... will post some with what ever I end up with ... as I was born in 1960, a classic styled Z3 seems appropriate for my generation & understand that some younger people may not be into that... each to our own ... including me
