if you can find the OEM M3 bars and bushings at a good price, but they are kinda hard to find. Might be easy to go with aftermarket parts

not really unless you are talking hollow sway bars, but they are definitely more expensive and not worth it for what you're doing.

Would you recommend used M3 sway bars with M3 bushing?
Recently I found also H&R sway bar set 27 and 20mm but of course not very cheap.
I'm just not sure what would be better option and result in better control of the car and not loosing all the comfort as well.
If you have the b12 Kit, you should get the Eibach swaybars for $309.99. They are tuned to the springs in the B12 Kit

If anyone is interested, I have a front sway bar that came off a E90 M3 and comes with bushings and mounts ready for install.

Unfortunately, it wont fit my 09 E91 328i since its xDrive.

Anyone interested send me a DM!

I wanted to but information from Eibach says that production is stopped, not sure when it will be renewed so I bought M3 sway bars from ebay.
Hopefully it works well too.

Idk how much stiffer they might be vs Eibach Kit. Certainly, they are cheaper than "new" front and rear M3 swaybars, that's for sure.

What was your impression after installing them?
What suspension are you on?

I may have a H&R rear sway bar for sale but I won't know until I install my UUC sway bars.. I will update the thread when I know more.

,I have a 2011 e92, with the B12 kit installed. Much better than the sport kit the car came with. All is good but there is just a tad of looseness out back. Will the sway bars you brought up here solve this issue? Also, are they at all difficult to install?

The rear bar is a PITA. We dropped the rear subframe to get it in

A couple things can help with a loose rear end.

Drop the rear subframe :

Upgrade your subframe bushings to M3

Upgrade your differential bushings to M3

Change out the remaining control arm bushings

There are Kits you can buy that have all the bushings you need which include the 4 upgraded M3 bushings.

With the subframe out, that's when I would change out the rear swaybar. Also, you should have adjustable swaybar links. 1" longer up front than stock & 1" shorter in the rear.

A "while you're in there", while the subframe is out, that's when one would do SS Brake lines. The rear SS lines are nearly impossible to get to w/ out the subframe dropped out of the way

This isn't an issue where the rear end is worn out, and out of control. I am looking for that last bit of firmness without an M3 hard ride. The differential bushings are new, as I upgraded it 3 years ago. LSD 3.46. Ditto for the brake lines. I still want my car to have that BMW ride. I have ordered the sway bars. Hoping they give me the last bit of what I want.

Sounds good. You'll need to lower your rear subframe maybe 4-5" in order to take the rear sway bar out & new one in.

I personally don't think the M3 subframe & differential bushings are overly stiff. If anything the rear end feels more planted.

I can dig more planted. I have a 3.46 LSD, with about 540 at the wheels.

The new sway bars were installed yesterday after having them powder coated black. Sorry guys but the red color is too ricey for me. So far so bueno. Things seems to have firmed up a tad without losing that BMW ride. Can't wait to get it out on the highway and see how she feels.
