If anyone has more options to add, please reply to this post.

Dinan just raised their price for $499 to $549 so I don't think we will be getting any reviews on those....but here is a video where Steve explains the "Toe Steer" effect on the M3. Same principle applies to the 335i, expect that the OEM M3 vs 335i arm configuration is different -

Another option is to purchase BMW Motorsport group N bushings from Turner Motorsport and press them into your OE toe arms. I wouldn't use polyurethane for control arm as they'll get squeaky.
I'd avoid any aftermarket toe arm that uses a spherical bearing joint. I've not read one complaint about Megan Racing's toe arms so they'd be my choice from your list.
