Ok, this one has been opened before, I am sure of that...
1) The technical question: What is needed for the conversion? What parts must I get?
2) The less technical, and more "a matter of driving feeling" question: What is your opinion, is it worth to do this conversion when the car's engine is not as powerful as the 323i? I mean: let's say that stronger brakes are not what I urgently need. Are there other differences in driving by making these changes on my rear suspension?

Bought it recently for my car, what you need is the folowing stuff:

* rear subframe
* lower control arms
* rear struts
* rear calipers
* handbrake cables
* some nuts and bolts
* new rubbers

Sub frame is the same

you need new braek lines as the disk braek are different, also the 323i propotioning valve.

Thanks!
And...about question no.2?
Are there differences in driving, handling etc. (except for stronger braking) due to the upgraded suspension?
I am asking that because if I remember correctly, someone in a thread wrote that road contact is much better with this upgrade...

Proportioning valve? Damn it! I have every thing, except that thing...
Without it would disc brakes get more or less pressure than it suppose to get?
There are aftermarket ones, but they are a bit expensive (100Eur+), so may be from E30,E34 it would do a trick?
