I have do a search found some great answers. And I have read up on tirerack's site and on Bilstein's website. But now I would like opinions based on my specific concerns.

I have a E34 525i with stock suspension and 18inch Style 65 M5 wheels. I think they are 18x8 or 18x8.5 I don't remember. But they have 235/40 ZR18 tires on them now. Would Bille HDs or Sports be better with that and Vogtland springs?

I plan on Vogtland springs with (40mm front/20mm rear) drop and Bilstein Sports or HD. I don't know whether I should get the HDs or the Sports. I have heard people doing both. I want better handling and a lower drop, but I would like a fairly decent ride all things considered. Also I will do Racing dynamic sways when I do the setup.

Is one or the other a harsher ride? Will one bottom out more than the other?


Thanks in advance for the help!!!




Also, should I replace my upper strut mounts when I do this?
