i've searched for long while, and never found the answer to this ?

For Brembo BBK what is a better fit for our car up front a RE30 with 17x7.5 +43 or
17x8 +44. Looking for the rim to be flush and at the same time which one has more BBK clearance.

For the CE28N I understand I may have to run a 3mm spacer for the 7.5width for adequate clearance. They seem simlar but I don't know how much more spoke clearance difference there is between the RE30 and CE28N.

Thanks in Advance!
