New Alloys for my Z4

OwenMeasures · 01-03-2019, 02:37 PM

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.

Ref the following: https://www.e90post.com/forums/forumdisplay.php?f=12 lower the ET further out. higher closer in. I just up-sized to the following: Fronts 8.5x18 ET 30 with 245x40x18 PS4s. rears 9.5x18 ET 35 with 275x35x18 PS4s. Need to compare to what is on the car now.

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

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.
