18" offset question

Hi everyone

First post and also new owner to an e92 335i 2007
I've searched and found a lot of info on offset and side

So far the ideal info I've found is:
FRONT - 18x8.5 - 235/4018 ET30
REAR - 18x9.5 - 255/35/18 ET25

I have found a set of vmr v710 similar but offset are 35 front and 22 rear

Will I get into any issues of running?
Will be also for coil overs and lowering a bit (not slamming)

2nd questions is I do plan to track the car and I know there is a form-flow version of this rim. I'm not concern about weight but more so strength. Would the regular cast rims v710 be fine for track or should I look at form flow to forged for tracking?

Thanks for the info advance and sorry if I'm repeat anything that's already been post

Seems like M3 fit wheels, if so they will be too aggressive to fit.

Hi there,

While the widths you listed are ideal for your application, those offsets seem a bit low compared to what is typically ideal for the non-M E92 chassis. I would recommend something along these lines as an alternative:

Front: 18x8.5" ET35 or ET38 with 235/40-18 tires
Rear: 18x9.5" ET35 with 265/35-18 tires
  • Direct fit.
  • 245/40-18 front tires can be used.
  • 275/35-18 rear tires may require rolled fenders and/or negative camber depending on ride height.

You can run an 18x9.5" ET22 in the rear on these cars and while it will be a more flush fitment compared to an 18x9.5" ET35, you will typically have to roll your fenders to fit a 265/35-18 tire. The 18x9.5" ET35 gives you a bit more fender clearance to run a more aggressive tire without further modifying the car. Even with coilovers and a mild to moderate drop in ride height, this setup will typically be a direct fit on a Pre-LCI E92.

While I cannot speak to the VMR wheels specifically, I can share that our Flow Formed wheels are designed and tested with regular track use in mind.

Hope this helps! If you have any follow-up questions please let me know.

Amazing info! Thanks so much!

That will help my hunt. Trying not to break the piggy bank on rims (super speed rims might be an option now for flow forged instead)

Will be posting a full build threat soon

**update**
Looks like I'm gonna go enkie raijin. Exact size mention above and the style I want and I trust this to be for track while still being in my price range.

Here we gooooo

Similar question here - having trouble with offsets.
I'm getting new wheels for my 2009 E93, either 18x8 or 18x8.5 (I know, not exactly pushing the envelope here) - seems like "Standard" offset is mid-thirties, and as wheels get wider, the offset goes down, is that right? Should I be looking for 35-38 offset for these size wheels? I found a set of nice style 270M's, but they are 22 offset - that is too low, and might have issues with brake clearance, right?

Thank you!
