Z4M wheel options

So I find myself looking for wheels for the Z4M. I want them to serve 2 purposes.

1. Be lighter than the OEM wheels
2. Look better than the OEM wheels

And they must be 18" since I have tyres ready for them. They will become my daily wheel setup. The OEM's will go into storage until the car gets sold one day.

Here are some pics that I would like to share and please feel free to post more pics with suggestions. I'm not 100% sure on the size requirement, but if they fit on the E46 M3 then they'll fit here as well.

Option 1 - stick to OEM



Option 2 - My personal favourite Style 313 in 18"







Option 3 - CSL or 1M rep (as good as the look is I feel it's reserved for the E46)
