since swapping the rear suspension on my 320 (complete 323i - diff, trailing arms, brakes, struts & shocks)I now have a right hand side rear wheel that sits out quite a bit at the bottom. Looking at the ETK database it appears that the 323 has eccentric rubber mountings on the suspension carrier (where trailing arms mount) as standard fittings, wheras the 320 has standard mountings or optional eccentric ones. Is this so? I thought I may just need some new bushes, but how do you get eccentric ones right?
