1M vs M3 E92 Rear Sway Bar

[froop]

I was looking through the BMRautowerkes website and noticed that Stu was selling both the 1M and the M3 E92 rear sway bar. Both are listed at 22.5mm.

I did a little bit of research on RealOEM and found that the all the bushings and screws etc are the same but the bar itself is a different part number.

1M Rear Sway Bar

M3 E92 Rear Sway Bar

Does anyone know the difference between them and which one would be more appropriate for our 1ers and or for E82's vs E88's?

(Yes, I know I could have just shot Stu an email but I figured I'd see what everyone's opinions were whilst letting people know of some new products/options)

I would love to know as well as I'd like to do it when I do the rear bushes. I asked Harold if they are the same ages ago and he said "I think it is a tad smaller than the 335i coupe/sedan bar."

I think the 1M sway bar would be a perfect application.

I couldn't seem to find any photos of the bars so if anyone has any and could post them up it would be much appreciated =)

I'd like to know too



I'd put my money on the 1M bar being better suited to the E82/E88 though.

Hahaha serious?

They haven't arrived yet? Once they do, be sure to take a photo for us

I just checked and the E82 1M and the E92 M3 both use a 22.5mm rear sway bar. However, the part numbers are different even though they look identical on realoem. The E93 M3 rear sway bar is 26.5mm.

The OEM 135 E82/88 rear sway bar is 11mm...

ohhh rear, my bad for always assuming people talk about 'front' on this forum

wow, 11mm up to 22.5 would probably be farrr too much for a mild setup.

I've heard differing opinions on this. Still trying to figure out what's right haha.

Some say only do the rear if you have an LSD, others say it's ok to do the rear as long as it's the E92 and not E93 M3 bar.

I'm thinking of doing the rear when I do the bushings. So I don't have to get the subframe dropped twice...

I guess if the rear ends up being too stiff and I get a lot of oversteer I can always get an LSD installed later.

Stiffer rear bar would be a good way to future proof yourself if you're planning on an LSD at some stage...

Makes sense to do it at once, paying to have the subframe dropped twice doesn't.

Till then report back and let us know how it goes with the stiffer rear sway sans LSD

You'll know when I do. I'll probably get the 1M bar from you once I get the money =Þ

I wonder if one is hollow - or if one has a "neck" in it like the 135 front bar has.
