Rear sway bar options

dre99gsx · 11-23-2022, 05:21 PM

Been researching my options for rear bars. Obviously I could go for an H&R unit for nonM

H&R 21mm rear sway with 6 adjustments
33551094544 15mm bar (2.0i, E46 328i)
33551095758 18mm bar (3.0i, 3.0si, 330i, etc)
33551094545 19mm bar (Sports suspension) - what came with my 3.0si

I have experience on the 19 and 18, and may try the 15. Not sure if the 21mm at its weakest setting compares to any of the above, but it would give me more adjustability.

Thoughts?

This is in addition to more info in this thread:

I didn't see the 15mm option listed, so it's yet another one we can choose.

True, although they are much larger. I was looking for what's available OEM. Apparently US doesn't normally stock the 15mm bar (seems like it's a European only part). Was looking around for the smallest bar I could find...
