New Alloys for my Z4

Hi,

Looking for some advice, I have a 2009 23i, I want to put on some new alloys, the one I am looking at are the BMW 461M Alloys, I wondered if there is anything more too then fitting.. going from a 17 to an 18, can anyone out there tell me if they will fit or not.

461M (235i) wheels are
18x7.5 +45
18x8.0 +52


Going against z4's style 293 wheels as basis, offset calculator says you'll lose
F: -10mm inner clearance, -22mm from outer
R: -6mm inner clearance, -18mm from outer


It'll most likely clear brakes and etc on the inside but its going to be VERY sunken in and look terrible. Would not recommend it.
i suppose you can get 20mm spacers to offset it but it'll never be close to flush

BMW Replica 622 Style

Found these on ebay. Couldn't be happier. 18 inch which i prefer. Lots of choices. Its a lease, so i got 4 sensors, rims and stock size tires (all season) Works best for me in the northeast. Total cost $1200. Stock rims and tires in garage with 300 miles on them.
