M5 Sway bar fitment problem on a NON Msport 535

I took my 2012 535i X drive (non M-sport) to the shop to get a front M5 sway bar and a rear 550d sway bar installed.

The rear bar was a perfect fit.

The mechanic tried to fit the front bar, but said the brushing wouldn't fit properly because it didn't sit flush against the frame of the car (I think its the frame that the brushing is screwed into??)


He pointed out that the brushing so too close to curved portion of the bar. Does that matter?
Could he just of shifted the brushing?

I tried to search the forum, but it appears all the 535's with M5 bars installed are M Sports, so I'm wondering if there are any non Msport owners who have successfully installed the bar.

Just want to make sure your M5 FSB came with new bushings right?

Sorry for been off topic here but I have a question:

What is the difference between the M5 Sway Bar and stock that makes the handling so much better? I understand not having one and putting one in vs. replacing it?

I have 2013 535xi non-MSport and wondering if it will fit on mine. Please update with your project.


Thank you

Not sure what your mechanic means by not sitting flush against the frame?

Is there a gap between the bush and the frame or is the bush to large?

Remember that there is a piece of metal that sits between the frame and the bush (it's clearly visible in Alan I's photo, just on top of the foremost red circle). This piece of metal holds the bushing inside the U-shaped metal tab that surrounds the bushing. Without this metal tab the bushing will have a lot of free play and won't sit flush against the frame.

But a bit strange if your mechanic didn't notice these tabs when he pulled out the original sway bar...

Is he trying to install the front sway bar with the suspension loaded or unloaded? The front M5 sway bar does not fit properly unless (front) the suspension is loaded (i.e., the weight of the car is on the wheels).

I had no problems fitting a M5 CP front sway bar with both front wheels in the air...

Congratulations!
Others have reported having problems fitting the front M5 sway bar with the suspension unloaded. Start reading at post #281...

I installed mine with the suspension loaded.
If one side is loaded and the other not, then it surely won't fit.

But, at least on my car, the two sides matched up without any issues at all.

The sway bar is fully moveable up and down before attaching it to the links on either side. The links on each side is also in the exact same height when both wheels are unloaded (or loaded on a level surface).

But I don't think this is the issue the mechanic was having. The OP said the bushings wasn't sitting flush against the frame.

Okay, then all I can think of is that the OP has the wrong part. The correct PN is 31352284460 (the correct bushings and brackets are included on the sway bar)

Thank you
M5 sways are thicker, so they're more rigid and keeps the car from rolling so much when driving around corners.

Yes, that looks correct. It should fit perfectly.
