Wow this is really eye opening thread. It's amazing the weaknesses you discover once you start pushing the car beyond stock levels. I've got a 325 e90 and was planning on upgrading. I can already feel the thrust arm bushings loosening up and I'm sure the other bushings and mount will start to go soon as well.
I just hope there isn't too much difference between the e90 325 zsp and m3.
