This is mine on Eibach Pro and Bilstein B4, freshly installed in this photo. Dropped a bit more now after 2-3 months of driving. Ride comfort is almost identical to stock, if I compare it to before, when I still had the original struts from 2000, this is miles better.

 

I have the eibach on stock shocks and I completely agree with the above post ^^

 

Mine sits about the same as #2. Same comment about everything taking a few miles to settle.

 

For some reason (no longer produced?) Eibach no longer shows the E46 Pro-Kit springs on their website.
I would verify in stock with any vendor before buying.
Here is a bimmerworld link for reference: E46 Eibach Pro-Kit Spring Set

Also, the Bilstein B4 shocks/struts are for stock springs and ride height.
For lowering springs you want B6 or preferably B8.

 

Yes Bali technically you are right, but the stock shocks will accommodate some drop effectively, or the b4 ones. Yes, there might be some loss of lifespan I guess, but the eibach pro are pretty mild drop wise.
To the op, don't consider the eibach b6 or b8, they are good quality but too harsh and will ruin the ride

 

The Eibach Pro-Kit is specifically designed to match the valving of the M-Sport SACHS shocks, so those are the ones you should be using when going Pro-Kit. I don't have stock pics, but this is what my current setup looks like with the Pro-Kit:

 

i need to do a suspension refresh in the near(ish) future, and I'm looking at an OE (sports springs / shocks / struts all round) or as close to OE solutions (eibach springs / sports shocks & struts) as described by here by Galopolis. Like OP, i would be okay with a little lowering, even if it's just the ~15mm of OE the sports package (226A). That said, I can't find for the life of me the correct product number for the sports springs after trawling through every suspension related thread on here, nor on realoem... can't even find the standard spring PN!

I would really appreciate if anyone could help me out?

OP, sorry to thread jack, so here is a little gift in return

Consumers can't access spring numbers because they are unique to each car. The springs are going to be different based on how the car is configured. You will have to contact the dealer and provide your VIN.
