Suspension advice needed please

1 AKY · 08-08-2019, 12:08 PM

Hi All

pre-LCI e90 330d M57, approx. 95k miles.

Rear coil spring snapped recently with the other not far behind as it's also corroded). So a good excuse to refresh the suspension which as you'd expect, isn't as 'compliant/comfortable' as it used to be.

Have already sourced Eibach Pro springs, Bilstein B4S shocks and bump stops which seems to be the obvious. Whilst it's being taken apart, what else needs to/must be changed? If budget permits, what else would you replace?

I've had a look at the threads on here, along with parts diagrams on bmwfans.info, but I'm just getting more confused.

OEM, Lemforder, Febi, Bilstein?

Best place to source? Do I also need to buy nuts/bolts etc?

Any help & pointers would be greatly appreciated.

Thanks in advance.

You may want to replace the top mounts whilst it's all apart.

I now think I've a rough idea of what I need in terms of top and bottom mounts, both front & rear. Would you recommend Lemforder, Sachs or another brand?

Thanks....but I was asking about the top and bottom mounts (rather than springs/shocks).

Use this to find Lemforder replacement part numbers then google the part numbers for the best price.

Replace anything rubber. After 11 years and 95k miles, it’s end of life.
