E46 M3 Rear Bumper Sag Fix: Please Help! (with Pics)

Just spent the last 6hrs trying to install these brackets to fix the rear bumper sag with no luck!

Attached are some photos (sorry for the quality) but I have no idea where to place them or how to install them once I remove the inner fender guard. Can anyone help?

This is very frustrating and with your help, maybe there is a simple solution. I appreciate the help!

Thanks!

Part Numbers:

Left Bracket- 51127896162, Right Bracket- 51127896161

Real OEM Link: Part #20

My Ride: '04 M3
Just found this thread based on the one from last summer...

I've noticed many M3's with this problem but mine was fine until some jack-hole rear ended me March '08. The body shop that fixed my car was suppose to be the best around the South Puget Sound with high end vehicles (Paramount Centre) and they gave me the same 'it's normal' runaround. My gap is now about like yours. I've taken it back several times but they are using different clips, that don't seem to be beefy enough, between the bumper cover and rear quarter panel.

I'll take my car back in, have them get these parts and install... I'll try to get some pics & description on how it's done, but my confidence in these guys is limited. I may be doing it myself & would also like a DIY description from Philly or somebody else - thanks!

That hook part looks like it must go around a bolt or something

I bought those brackets a little while back hoping to 'tighten' up my bumper...I was unsuccsessful at best and decided to just deal with it. My car is 5-6 yrs. old, its body settle...

I know that is not the answer you are looking for, but from my understanding this is a common 'problem' on these cars.

If you come up with some break through please let us know.

pic #5 is close, but youre holding the clip upside down, so flip it around and bring it all the way to the right [in the pic] and there should be a bolt to mount the hooked part to. the other end of the clip will attach to the plastic of the bumper. i know this cuz i just did it on my car!!

Thanks for all your help guys, rby330ibmw, I do not have a bolt to fix the position of the hook if I follow your advice. Looking into the inside of my fender, there are not bolts or hooks to fix the position of the clip. I got another response from Philly_Swedem from another forumn, check it out, he has pics:

Here you go

Well, there's no bolts om the E46 M3 (not on mine anyways)

The clip holds on to the bumper AND fender and the hook rests inside the fender. That's how we did it on mine and its solid as a rock!

Good luck!

Just took my car out from winter storage for the year and I got enough issues with it (Low Coolant, Low Washer Fluid, Head Lamp Corner Bulbs out, Oil Change Due, Wiper Blades fried, and Clear Coat peeling off the roof-literally). Fixed everything so far today except the paint and wiper blades.

It's like you fix one or two things and five things go wrong.

Anyhow I noticed my bumpers are sagging at the creases and it seems I can fit my fingers in between the bumpers and fenders.

I vaguely recall a DIY for replacing the bumper brackets when adding M3 replica bumpers and also tightening up brackets or replacing them to fix sagging bumpers but I cannot find any info on that.

At this point I don't even know how to remove the bumpers much less tighten them up.

Any ideas?

Here is my car today:








And here is what I want for my car!

Notice the almost seamless seam on this 2003 330xi:

You can see more pics and see how I installed them. I advise getting the parts that I listed and installing the same clips onto your front bumper in the same manner I installed them on the rear.
