What car you got?

I've not heard of eccentric trailing arm bushes, I done mine (with Polysport bushes) and they're all concentric (the hole is in the centre of the bush). I changed the front wishbone bushes to M3 eccentric bushes, but I don't recall an option for eccentric trailing arm bushes. I also can't see the benefit, nor how eccentric bushes would fit, they're small, long bushes, rubber (or poly) outer with a steel inner bush. :?

P.S. The trailing arm bushes are a bugger, especially if they've been in there for 15 years (as mine had). You have to drop the whole trailing arm, which means disconnecting the rear brake lines (well it does on a 325i), etc. Getting them out is a bugger, better if you can get the trailing arm onto a bench. And be sure you put them all in facing the correct way (can't remember if they face out or in, but you'll see which way round is correct when you take the old ones out). Best of luck with this job, could easily take you all weekend!!! Depending on what tools & facilities you have at your disposal... :roll:
'89 325i - was an SE but not anymore, was bronze-beige metallic (yeuch!) but now techno-violet (thankfully)
'89 Toyota Corolla GTi-16 - track, hillclimb & sprint car (yeeha!)
'08 Buell XB12Ss - American engineering at it's 'best'... good fun though

Sorry, forgot to answer your last question.

depends on what you want really, if you want hard driving / track use go for polysport (expensive though), if you drive more sensible like then GSF/Euro are fine. I must admit though that the bushes I changed (practically all) are either poly or M3 spec from "the stealers" with a nice 15% discount I negotiated with my local dealer, you get at least 10% off if you're a member of the BMWCC and they don't necessarily bother asking to see your membership card which you probably "left at home" anyway).

P.S. BMWCC members also get 10% off at GSF :wink:

The eccentric bushes are for correcting the camber angle after extreme lowering or accident damage.

The GSF bushes are fine, I've had them on my 2.7 for over a year now without any trouble.

I bought some standard replacement ones from GSF and have noticed they have less rubber in contact with the arm than the original ones that came out.
May be worth visiting the main dealer if there's no difference in price.
There is NO nucleus.

The rear trailing arms are only about Ԛ£30 from the dealers, I'd go with these, GSF/ECP bushes quality seems to be a bit of a lottery.

Apparently I am going to need to replace mine on the passenger's side soon, what are the signs of these needing to be changed ?? -so I can keep an eye on them-
