Trailing arm bushes

[Alpina2015]

Hi all!
Im in the process of removing my rear subframe and changing all bushes ect. The rear trailing arm bushes that i got from the dealer are eccentric and i haven't a clue on what position to install them as they are not adjustable. my car is lowered also if any you guys got any experience please pipe up.
Thanks in advance shall upload a few pics of the beast when shes ready.....

Since having new tyres fitted I had the tracking checked and it was found that the rear was out. Existing bushes were checked and found to be ok, nothing else found amiss.

Realoem shows that my car (318is) has 2 eccentric bushes and 2 standard on the trailing arms? (Did previous owner fit 4 standard)?.

Opted for Powerflex adjustable bushes (NOT cheap) and after much faffing about ('c' spanner made of putty) I now have the car tracked ok. Total cost near£400!!

Jheeze £400!!! I've already got the oem bushes so just going to stick with them but just seems odd why there not adjustable?

Standard trailing arm bushes aren't eccentric and should give close to correct geometry when fitted to a car. However, things can get bent, and eccentric bushes are sold to correct any incorrect geometry when this is discovered.
To install eccentric bushes you need to measure and record the geometry with the old concentric bushes still fitted, then use these figures in conjunction with the instructions supplied with the eccentric bushes to decide at what rotary angle they should be inserted. Without this data, fitting the eccentrics will be guesswork at best.

So Brian, correct me if I'm wrong but if 'all' trailing arms had concentric bushes as standard, then fitting eccentric (non adjustable) bushes to compensate for alterations to suspension geometry is fraught with difficulty and you'd better have deep pockets.

Not really, but you must know what you are doing and what the car measures with the concentrics in. Otherwise you are just shooting blind.
