Hi, someone know tell me if the rear sway bar BMW M3 E93, could be installed on a BMW 335i e93? Logically include the new silent blocks and sway bar mounts.
Thanks

I don't know about it being "logically the new silent block"

yes it can
it is a very common mod...even for non vert guys.
the e93 is the thickest OEM so even coupe 335 owners go for this.

Can anyone point me to where I can read up more on how bias (the sticky in the Suspension forum is where I got this info from) affects things, and how I would go about deciding which bars to get, based on that?

I've got an E93 with factory sport package, so which one of these would it be?

BMW Stock ZSP: 26.5mm (38291 mm^4) /13mm (2803 mm^4)
Biasing: 93% / 7%

OR

BMW Stock Xi or e93: 26.7mm (38291 mm^4) /15mm (4970 mm^4)
Biasing: 89% / 11%

Either way, I suppose it's more or less around 90/10.
.
.
But I see the BMW Stock e93 M3 is:

28mm (46380 mm^4) /23.6mm (23000 mm^4)
Biasing: 67% / 33%
.
.
So when picking the bars, should I go with a 90/10 bias split, or a 70/30 to match more the E93 M3?

Thanks for any help guys!!!

Be careful with those calcs, for example the XI front bar is approx 26.5mm but only at the ends. The middle long section between the bushings is 22.5mm, so the whole thing beahves more like a 22.5mm bar. Plus I think it is hollow.

On a non XI my choice would be go with same F & R M3 bars for your platform. Ie for e90/92 go with those, e93 get the bigger rear bar.

Other thing is rear sway bar install on these cars is non trivial read up on it before you commit. You must drop rear sub frame. And if you do that may as well do M3 subframe bushings too.
