Default 2021 M550i Front & Rear sway bar - 06-25-2021, 02:55 AM

Apologies for staring a new thread but I didn't find one currently.

Question:

Does any one know a company that makes sway bars to fit this car? Will sway bars for another 5 series fit? My research as found nothing or I just don't know what I don't know.

Any help is welcomed.

Oddly I was looking into this last week. It seems that the M5 Comp bars will fit with adjustable links from a vendor like 'Hardrace'. I'm a fan of an OEM upgrade as you know for sure its subjected to proper R&D on the vehicle in every climate and situation.

Do you have Dynamic Drive? The 5, 6, 7 and 8 series all use the same adjustable front bar with Dynamic Handling or M Professional. That bar is not replaceable with aftermarket without serious work

If not, the 5, 6 and 8 share a front bar.

It doesn't look like the rear bar is shared with anything. So unless Dinan makes a replacement, M5 may be the only option. It has a 30mm bar vs our 25.7mm.

You guys are a wealth of Knowledge, thanks. I did not buy the handling package if that's what your asking?

I have Dinan springs on the way as I don't want to lower much. From what I have been reading upgraded bars will do wonders for body roll. I was even looking into strut tower bars and found nothing.

So without the handling package I can use M5 bars? F10 right?

Not sure how much of this applies to us, but just something I came across. https://www.r-parts-store.com/BMW-5-Series-Sway-Bars

I'm actually shocked that H&R doesn't have sway bars for the G30 yet.

All,

FYI. Hardrace has confirmand that their rear sway bar fits (only) the front they sell does not due to xdrive. I asked if they could confirm other model sway bars that might fit that would be an upgrade and they could not.

Here are the detentions of the sway bar of my car and the one hardrace sells.

The diameter of the rear sway bar stock is 24.5 mm.
Our rear sway bar is 28 mm.

I will find a front somewhere damn**

Guys,
I just purchased a rear sway bar from hardrace here in Germany. I feel all I will need is rear not a front as our cars understeer. Apparently a rear sway bar can help fix this on these AWD cars.

Hardrace for the win. Fit perfectly, and car is flatter in turns with noticable less body roll. Do it guys... It's worth it. Thanks to boosted who recommended hardrace.

Finished up the rear axel today and man what a pain in the @$$ to put these springs on, by myself I might add. However, the ride afterward is great. I turn on a dime it seems now. Adding a rear sway bar and Dinan springs has done wonders. If anyone's has install questions just ask as I installed both items.
