I too plan to keep the car for a long period which is why I want to get the handling sorted. Tomorrow, weather permitting, I should get the parts replaced and be able to report back with news. I had originally just planned to replace the dampers and strut tops in the spirit of doing one adjustment at a time, but having seen the drop links' condition it doesn't make sense to leave them unchanged. Powerflex is certainly a consideration for the main ARB bushes which will be the next thing on the list, although the ones on the car currently don't look damaged or worn (I'm sure they are though).deni2s wrote: Maybe powerflex don't have droplink bushes, but I replaced all bushes I could with poly and I am very happy. Didn't replaced bushes on roll bars, but probably will do that too later. I have poly bushes for two years, no problems since. Car feels stiffer, maybe even a little bouncier than with rubber bushes. I think it's common conclusion on z3 forums, that replacing rubber bushes with poly is improvement. The only bush you should keep OEM is differential bush, poly bush may increase car vibration at idle. If I wouldn't want to keep the car in long term, I wouldn't switch to poly (oem parts are cheaper), but I plan to keep that car for long period of time, so I invested in poly bushes - they also last much longer.
I know that the trailing arm bushes need replacing too as when the alignment was checked it was out at the back and this is the way to correct it. That looks like a fun job which is why it's at the bottom of the list
