330/325 strutbrace won't fit on a 335. ADHD tried and got lot's of rattling noise.

Thanks for the info, I read his posts. On the BMW website in the accessories section, an STB is listed for the 335. I wonder if this STB will work without noise. Unfortunately no part numbers were listed so I couldn't compare.

I wonder if we can get somebody with a metal/machine shop to re-create this strut bar for members. It's certainly not a high tech piece of equipment, and as long as the dimensions are right, should be no-brainer for a shop to reproduce, and could be done for a lot less than $200+.

I've got a next-door neighbor that owns such a shop...maybe I'll talk to him. I'm sure he'll want an original so he can get the dimensions and angles from it.

Does anybody know the material of construction of the OEM strut bar? Is it aluminum, or 316, or?

its aluminum..

side note: i went to install and i have a inverted hex bolt on the right and left side. im trying to find the correct size. did anyone else run into this problem?

what do you mean an inverted hex bolt? are you talking about the sizes? no issues here...i had all the pieces required to remove and tighten the new bolts

ok my friend who works on cars all the time said that its an inverted hex bolt; imagine a hex(star) but inverted. its like a star but it has to go over it like a bolt, not into it like a regular hex. he has seen them but its very rare. i cant find this anywhere!!! help!

Do you mean its got a torx head on it? I'll have to look in the AM.

yep sorry i meant torx! wow im drunk sorry! i cant find this socket in my tool box. help would be appreciated! if anyone is local, a 6pack would be given.

ok found the bolt at sears(well at least thats what the told me) but how come no1 else has this on there strut?

I just got a note from the guys at Morristown -- they are great, best prices, super fast, good info -- regarding the strut brace for the E90 335. They say that it fits the E90, but not the E92. Has anyone installed the brace on an E90 335?

OK looked at the strut brace bolt, it is an odd one like fizzle described, a hex bolt but with indented sides (rather than flat surfaces on the bolt sides, they V in the middle). I forget the name for them.

yea, i know many people who put it on e90 335. just went to sears and got the set : fuckin 39.99!! its craftsman so lifetime warranty, but i doubt i ever use it again.

link to Sears product?

Great news, but can anyone confirm the fitment on a 335? Thanks

fizzle, did these people experience any of the noises/fitment issues? Thanks.

i doubt it. the e90 330 and e90 335 are the same body so what would be the problem?

Apparently the height of the engine cover is higher in the 335 causing the noises/fitment issues.

not according to crown auto:

51 71 0 406 937 is the part number if you go to parts.crownauto.com and type in the part number it comes up multiple times for e90 325, 328, 330, and 335 as well as the e91.

I agree and have done this search. The issue arose when a member actually installed this bar on a 335. Since I last read that post about the noise, I have not found anyone with a 335 that has successfully installed the bar without the noises (at least not anyone that has staked that claim). I am looking for confirmation by a 335 owner that has successfully installed the bar and has no issues, noise or otherwise. Thanks.

i got ya. well your best bet would be to buy it try it and if it doesnt work send it back to morristown bmw. i dont understand how it could rattle; sounds like someone didnt install it correctly.

From what I understand, once the engine moves/vibrates contact is made between the STB and the engine cover. Thanks for your input though. Please let us know how it feels after you have a few miles logged. Thanks.
