Broken springs on my old Z3

[GazHyde]

Drove up to my mates house to help him change the rear springs that were part of the failed MOT last month. Couldn't help but notice that both springs had broken in exactly the same place on the bottom. Not only that, but the fractures were almost identical too! Design fault? Coincidence? Paranoia?

New set of springs bought from Euro Car Parts, and the back end feels much less saggy than before (well it would have been rude of me not to take her for a test drive afterwards!)

E36 3 series have the same issue as I've seen that on a few, not sure if the springs are a shared part?

I doubt if it's a design fault. Spring failure mode is usually triggered by fatigue under normal conditions
Without knowing which failed first and why it is difficult to be objective.
Failure of one inevitably leads to extra load on t'other side resulting in double failure.

(did you not notice the lop-sided stance ? . )

I dont think its that noticeable
My brother drove around fo a year in his Z4
And he had to walk past it in the drive every day
That was just one, they advised change both

Would it be lop-sided if both rear springs were broken? :-\

Never mind your old Z3 Gaz, Hows the springs on your Z4 after that loud bang on last weeks cruise.

The car drives fine, but that of course doesn't mean anything! I will try and get her up in the air at some stage this week for a proper look. :-B

Its not really noticeable if the spring snaps as they tend too go at the tip and was a bit of a known issue on the Z4. I've known owners having them replaced under warranty only for them to snap again 12 months later. You might need too jack the Zed up and check where the spring seats at the top end.

I've still not got around to replacing my springs yet - I did get a couple of vastly different quotes from dealers. However, ECP are a bit cheaper

Question - are the springs on a (2.2i) Sport different from the standard (2.2)?

look at this thread... it might just be a design fault

Yes it's a common problem on them. Had one snap on my old E36 which shot out behind the car and luckily no one was following me as it would have caused some serious damage.

I'm sure its pretty common on Z4's too

The C class Mercs are notorious for this.
