Anyone else not have a rear sway bar ?

[chris82]

My car was in to get the subframe bushings replaced and also some adj. end links installed in the rear, only to find out that my car does not have a rear sway bar, is that common? Anyone else not have one?

Car is not M-Sport

128's(non M-Sports) didn't come with a rear sway bar. I think that's why BMW includes front and rear sway bars with their Performance Suspension kit for the 128i.

Oh, well that explains it. It's funny, I would have never known it didn't have one unless I was told, never thought the rear rolled that much tbh

I think the (non-m) sports package also includes a rear sway bar and not just the m-sports package according to http://www.turnermotorsport.com/p-18...parts-kit.aspx. Either way, I can check mine while doing my diff fluid change if you'd like.

I believe the MSports package does have a rear sway bar.

M-sport package on the 128i changes the shocks/springs/wheels and also adds a rear sway bar(besides the interior trim and seats, headliner, etc).

M-sport on a 135i is just a trim package(sport seats/headliner/wheels/higher speed limiter/etc). Suspension is the same on non M-sports.

135i E82 comes with a 11mm rear sway bar
the 1M rear sway bar is 22.5mm
the new m235i rear sway bar is 15 mm

i just got myself a 15mm eibach rear sway bar for my 135i, i will have it installed in a few weeks.
let see how it goes, and go on from here

Damn, 22.5 on the 1M?

I've always read that a big rear sway bar isn't all that good if the car doesn't have an LSD. Specifically it can cause the inside rear wheel to lift. Not sure how our car's ediff will handle that.

My car's inside rear wheel lifts already on hard hairpin corners. Stock rear sway bar, upgraded shocks and springs on Super Sports. You can feel the traction control do the stutter.

Anyone want my rear adjustable end links? will be in the for sale section shortly

My 2008 128 coupe, with sport package has a rear sway bar. I believe it was before they offered an "m-sport" package.

I have a non m-sport that came with no sway bar, so I put an e92 m3 rsb in when I had the sub frame out. It is too f@cking stiff. At the time I was going to put an LSD in but later found that's not so easy on an automatic 128i. I have an e92 335xi rsb that I am going to swap it out with. I haven't measured it but it is probably 11mm from the looks. Just haven't felt like lowering the sub frame again. Don't go too stiff without an LSD!!

I run a 19mm rear.

And yes, rear tire life on the right surface will cause inside wheel spin. I ran on grooved concrete most of the time and had rear grip to overcome this. However on asphalt there were minor issues

Let me know how much, I might bite.

Does this mean I should not install my e92M3/1m spec rear sway bar?
How bad is it until you get a LSD?

I'll let you know the differences this year, as I have a diff now.

On Dunlop ZIIs, it wasn't any issue. I think the hard sidewall helped the tires keep contact? Who knows

On RS3v2s, inside wheel spin started to be an issue, but it was surface dependent.

This was on RS3v2s on Asphalt

They're in the FS section for $90, plus shipping and everything, but I'm working something out locally now, if it falls through I'll let you know

It is most noticeable when pulling out from a stop with the wheel turned. If I don't hit the dsc button the trac control steps in big time. When I was on the track, I had no problems.

Yes until next week.

128 non sport = 0
135i non sport = 11mm
sport/msport = 12mm
1M = 22.5mm
