I also want to add the install for the M5 front sway bar is super easy. You can do it with the car on ramps in no more than 30mins and thats taking your time.

I normally DIY all of my parts but now with a baby I decided to let my shop do it. I watched the whole process and it was in and out in 30mins and that includes getting the car on and off the lift. Theres maybe a dozen small bolts that holds the belly pan up and once that is off you have a total of 6 bolts that holds the sway bar in place. Its in a area that isn't blocked by anything and you can reach all of the bolts with ease.

My stock front sway bar

First post from a new member - Many thanks to Alan. Great research and willingness to be a guinea pig. I'm a relatively new owner of a 2013xi, M-sport with DDC but no ARS. I have the Dinan springs and I'm going in for the Shockware. It sound like the M5 sway bar will round out the suspension upgrades well. Thanks for providing some great info.

Any luck on the 550GT bar Joe?

According to realoem it looks like we need the bar plus two bushings only.

The suspension just feels tighter and more solid up front and you notice it this when going over bumps and uneven roads. The car is flatter during turns and the steering feels alittle more direct/precise during high speed lane changes. Before I would anticipate the roll/sway movement but now the car just points to where you want it. It isn't a track car by any means but that wallowing feeling is pretty much gone or barely noticeable anymore. Nothing negative about doing this mod at all so far. Very pleased.

Sound good but what about the feeling on the rear end, dose it feel unbalanced?

Now with the rear bar.

Turns out on the 535 theres several sizes that the car comes with depending on options and if its RWD or AWD.

535i standard rear bar is 13MM
535i Msports rear bar is 14MM
535xi standard rear bar is 14MM
535xi with EDC/DDC rear bar is 15MM

I did not check this for the 528 or the 550 but you can easily do it with realoem.com

Since my car comes with a 15MM rear bar I will go with the 18MM F07 550GT's rear bar for a 3mm increase. Looks like you will also need to purchase new bushings with bigger internal diameter to hold the thicker bar. Hopefully thats it.

Alan

I check but the parts number are not the same for all 4 cars and also no info on how think the bars are but the image is the same for all 3 cars
will the M5 sway bar fit my 2012 528i car any one know?

M 528i - Use this site to cross reference which models share the same parts

http://www.bmwstore.pl/pl/katalog/pr...ni-z-pod-gumow

Part# 31356791924 is what comes on a standard 535i here in the US. When i plugged in that number in that website it lists a bunch of cars that also uses the same part and your 528i is included. This means since the M5 bar fits a 535i, it will also fit a 528i.

Alan

So the M5 1 should fit the M Sport too, right?

[Alan l.]

There is no difference between the mount points between the standard, msport or whatever so it will fit.

thats I will get this later on then

M5 confirmed for us his rear bar on his F10 M5 is 18mm. For those of us wanting to match the factory set up when upgrading to the M5 front bar, the makes the choice for the REAR BAR real easy- 18mm

[hyperboost]

if even@tischer can put together a package for the M5 rear sway bar, i can be the first and test fit this. especially for xi owners

[Alan l.]

^^ the M5 rear bar is confirmed to not be a direct fit by Joe@ptech. The 550GT however is looking like a good alternative since it is also 18mm in diameter

Alan

[hyperboost]

^^^ sounds great. Even needs to chime in here with some part numbers

Alan

So the 550GT rear sway bar will fit?

[Alan l.]

Waiting for Joe@ptech to confirm. He's waiting for the bar to arrive but looking at realoem.com this bar should fit the F10.

We tried this already and the bar mounts differently. Even with longer links, I'm not sure it will work.

[bodonx]

Any update on M550DX rear bar?

Sorry, I can't wait
