It seems like you got Bilstein when you had "Sports Suspension" + "M Technic". As far as I understand, if you ordered "Sports Suspension" + "M Technic" on a -03/85 car, you still got the same dimensions on the antirollbars as the standard ones.

My 320i has no rear sway bar and a friends m40 318 had none either.

There's a spring rate master list too

my 320 had nada bar too.. maybe different markets do?

I've seen 14mm rear sway bar bushes around, but not 14.5mm. simple mis measurement by others, or is there actually a 14.5mm and 14mm sway bar?
