I borrowed this from a Bimmer E46 M3 web site:
The M3 sits on 18-inch M-style alloy wheels (8.0-inch wide front and
9.0-inch wide rear), with appropriately sized high-performance tires (225/45
ZR - 18 front and 255/40 ZR -18 rear).
Will I be able to successfully install this combo on my 330ci? Is there a
reason why it won't fit? i.e. different diff :) larger/smaller wheel wells,
different suspension width? I'm not saying I want to run this combo, but
since I will be buying these wheels and tires via mail-order, getting it
wrong would be expensive. I don't have the luxury of trying out different
sets. I have to get it right the first time. The E46 M3 runs different size
wheels and tires in the front and rear. Is there a reason why doing this on
my car would mess-up my handling and not mess-up the M3 (as another said
I appreciate your indulgence while I get my feet wet with a BMW.
you do NOT have an M3..... you have a 330, deal with it!!!, you have 7" wide
mags, not 9", so you can NOT go wider than 225 with your setup.
if you want to spend another 4000$ on M3 wheels, get the right size and
I have told you 3 times to go to this website and ask, they will give you
the answer... http://www.bimmer.info/forum/forumdisplay.php?f
why do you keep reposting the same question here?
Just a note to all about the misconceptions regarding putting M3 parts on
Some will fit, some may fit, and some may work. But as a rule putting M3
parts into a 3 series is not a good idea. While some passive components will
not cause any harm (unless you are putting M badges on your 3 -the harm is
to your respectability) MOST ASSUREDLY DO NOT use any M suspension parts!!!
Even if they are a perfect fit the handling/ride WILL NOT be better, and
Rims and tires are a different thing. If they can be fitted the will work,
and depending on what you are trying to achieve they might fit the bill.
Suspension components are the biggest problem. People put them (and other M3
parts) on their 3's under the mistaken assumption that they are "better".
They are not. They are designed to work with the other components so unless
you swap out the entire suspension you will be in a world of pain.
Here is a link to the various rim options that are available. Find your
current rims and check the data for offset, then find the rims you are
interested in and see if the offset is the same.
I installed a set of M3 rims on my 325i, but I used rims from a 1995 car on
my 1994 car - all four are the same size.
I think your big issue will be that the M rims on the back will be too wide
for the 330. Having said that, it is entirely possible that this won't be an
issue at all. The front rims should fit find, in fact the front rims should
fit all four corners without any problem.
