Sway bars: OEM 135 VS BMW Performance

[Al3x_666]

ok, I just want to know if the optionnal BMW Performance sway bar is bigger or smaller than the OEM.

Each other are black painted...

When I look at my car the supposed BMW Performance sway bar look smaller than my OEM one in my hand...

m3 convertable bar is 28mm, coupe and sedan m3 of 26.5mm, obviously the vert bar is the way to go.

Ok...

So it means it gets M3 Coupe swaybar, and not M3 Convertible.

I think your reply can be found a few posts down in this same forum:

It appears that the OEM front say bar for the 135i is also 26.5 mm, but with a 19 mm kink in it which would obviously reduce the rigidity. So same size as the Performance sway bar, but not as stiff.

if you want it even stiffer you'll get the vert bar, its common sense..

Yeah, I was originally thinking of getting the BMW PS, but perhaps just getting the E93 M3 front swaybar might do the trick.... I'll get a better feel for the adequacy of the factory suspension once I take delivery in a month...
