Opening a new topic, since I can't seem to be getting an answer anywhere. I have a E92 2009 silver and loving the 313 style wheels 19"

I'm about to pull the trigger and buy them from here:

https://www.ecstuning.com/b-genuine-...h/36116787656/ manufacture code: 36116787656

https://www.ecstuning.com/b-genuine-...h/36116787655/ manufacture code: 36116787655

Cost around 200$/wheel

Doing some research (I was really surprised on the price) I found that these are possibly a good fit for a Z4. See here:
https://parts.bmwofsouthatlanta.com/...116787656.html

What I also found on the same site is that there is a 313 style that fits the 3-series:
https://parts.bmwofsouthatlanta.com/...117844343.html

The above part (bmw performance) is also available at ecs tuning:
https://www.ecstuning.com/b-genuine-...a/36117844343/ with a price tag of 570$/wheel

I would really appreciate some help here and apologies if this has been answered before, but I've done most of the searching on the forum and on google and couldn't find a satisfying answer.

Is the cheaper option going to be ok (both are OEM so I guess that from a quality perspective both should meet the standards) or the fact that it's meant for a Z4 means that the extra weight of E92 would be a problem

I've also seen that 313 are cracking a lot. Should that also be a concern ? I live in California so the weather shouldn't be a big issue. Mostly summer here.

Any help would be much appreciated.
Thanks

There are few versions of the style 313. These are z4 offset. Front might be an issue if car is lowered without aggressive negative camber. Rear is ok.

Thanks feuer!

Car is not lowered and not planning to, just love how these wheels look and need a change from the stock ones. I’ll probably need to double check with ECS tuning to verify that it won't be an issue, but other than that I think I’ll proceed with the purchase.

Every IS owner I know that does lots of freeway driving has ended up with cracked 313s, even OEM ones.

You drive a 328, I would go with an 18” wheel. I think the performance losses with a 19” wheel would make for an unpleasant driving experience. I went from a 17” to a set of 18” Style 197’s on my E46 and was happy with both esthetics and performance.

[brecode]

Hmm ok! Didn't know that 19" would be a potential degradation in the overall driving experience.

197's look pretty good and on the price range I am looking at. I think my main concern is the cracking. I do most of my driving on highways and use the car daily to commute to work and back so in the long run that seems to be an issue.

Between V710 (or V810) and 197 would you guys choose OEM ?

19's vs 18's... unless you're very discerning (professional skills) or drive the heck out of your car regularly, I doubt you'll notice or mind the performance differences between 18 and 19. Go for what you want and don't worry about it.. but yes, there will be a slight performance decrease re. braking, handling, etc when going to 19's, but very small in all reality. Biggest concern would be higher likelihood to crack with a larger wheel size.

As far as if those in particular work - find the wheel sizes and offsets for both the 3er version and the Z4 version and compare them. A lower offset, all else equal, will "poke" out more toward the edge of the car/fender. Many find this preferable (it's essentially what spacers achieve).

[atmosphericM]

The only difference on those Z4 spec 313's vs. 3er spec (higher price) is that the Z4 wheels are actually BETTER for you. 8mm lower offset means the wheel will "poke out" an additonal 8mm which is basically perfect for a more ideal look on the front. Go for it! You might end up wanting a small spacer for the rear wheels in order to make them "match" the "flushness" of the fronts.

I wanted these wheels but for being labeled "Performance" they're heavy and bend/crack very easily. I'd rethink it.

Having my 313's and now APEX 18's, if you're buying new wheels just get some light-weight, strong APEX wheels. A company who has a return policy per se if you do get a cracked wheel etc...

OK if car isn't lowered. Definitely not on lowered car. More aggressive negative camber would be required. I ran Z4 19" on my 335i for years and could post a photo from damaged fenders.

Asked my mechanic as well and he said he hasn't seen any cracked 313's so far and the offset should be ok with my car. Maybe a spacer like atmosphericM mentioned was his thought too. Thank you guys this was super helpful

This is very surprising to me. I run a more aggressive offset than those Z4 wheels and I don't have any issues. No, I'm not "slammed," but if you're tucking your wheels, you're going to have issues no matter what. I just can't believe that an 8mm spacer on an OEM wheel (effectively what the Z4 fitment equates to) is going to give anyone rubbing issues - cars are built with plenty of room there from the factory.

Are you sure you didn't have a square setup of all rear wheels?

Definitely not square setup, 8" front with 225, 9" rear with 255 tires, on yellow BMW Performance springs. Issue occurs while wheels are turn traveling over bigger bumps. Both my fenders have bents. This is with m3 control arms and -1.5 negative camber.
