Does anyone have a list handy of all the anti roll bar variations and which models they were fitted to? Specifically, what size front and rear ARBs did the late model 325i come with? Cheers

This would be an intresting list especially if it includes the uprated ones from the likes of H&R, Eibach ect ect ...

Late 325i? You guys got 20mm fronts and 12mm rears IIRC. In Australia we got a 14.5mm rear bar. Your Tourings received this larger rear bar I believe. Someone will correct me if I am wrong, I'm sure.

Koni do a 20/16 kit and the lads at UUC do a kit in a 22/19. H&R, Whiteline, etc., also do kits, though I can't remember the specs off the top of my head.

H&R- 22mm diameter front ARB and 18mm diameter rear ARB. 3 way adjustment on front and 2 way adjustment on rear.
Eibach- 20mm diameter front ARB and 16mm diameter rear ARB. 3 way adjustment on front and rear.

I have a list of all the standard ones somewhere, I'll have a look for it

There's no 16mm rear bar available from BMW, as far as I know.

6 cylinder cabriolets, the 324td and the U.S spec 318i cabriolet had a 21mm front anti roll bar.
