Honestly I think that with your car as of now the black rims might be too dark for it. Just my opinion. I think if you tinted the windows and put some nice silver like rims on it, it would look sweet. Maybe something like 19" BBS LM-R's would look sweet. But if you want a gunmetal or darker rim i do think that the CSL type rims look sweet in a darker color on a white car!
