My Ride: 2001 325i
Should I upgrade sway bars (subframe)?

Hi everyone,
I have a 2001 325i with 185k on it that I've owned since new. I've recently started to do all the work on it myself, and it's time for a complete suspension overhaul.

One thing I wasn't aware of on my car until recently is the propensity for subframe cracks. I didn't notice anything when I was changing my diff oil (apart from a destroyed diff bushing), but I'll do a more thorough inspection during my suspension overhaul.

I was planning on upgrading sway bars during my suspension overhaul but I don't want to put undue stress on the subframe and cause it to fail. I'm trying to save up for an F80 M3.

Any opinions or advice would be appreciated.


Edit: I also want to note that even though I've been the only owner of this car and didn't move for years during the time of the lawsuit, I never received a letter about it. Advice?

Are you talking about the propensity of (1) the unibody to tear as a result from the torque/fatigue of the diff carrier (aka subframe), or (2) the possible crack/fatigue of the swaybar-to-unibody mounting brackets.

(1) - The sway bar should put no undue stress on the unibody where it is known to tear. Again, it is the torque of the differential which fatigues the unibody. Get a second opinion, but I am pretty sure.

(2) - You can get sway bar mount bracket reinforcements. They come with the hotchkis sway kit, idk about others.

Good luck with the F80!

(1) is what I was talking about. Sounds like (2) is a good idea. I was planning on the turner bars.

Thanks for the reply and the well-wishes, I'm kind of stoked that the next m3 will come in 4 doors and have an i6.
