E70 xDrive 35i Lowering Options (Bilstein nationwide shortage)

[j3ffc00k]

Apologies if this has been discussed. I did some searches and didn't see any threads that were specific to what I want to ask:

I have a 2012 X5 35i with premium package, no third row, no rear air self-leveling suspension. My intention was to drop it slightly using H&R lowering springs and Bilstein B8 struts/shocks. I purchased the 1.25" drop springs many months ago but have since not been able to find the Bilstein B8 in stock anywhere. Apparently there is a nationwide shortage.

Any suggestions on comparable alternatives? If anyone done a full refresh (new mounts, etc.) and maybe has a list of what other parts they needed that would be great too! My thought was to keep the stock suspension and springs assembled so if I ever sold the car it would be relatively easy to return to stock height.

If nobody has a line on where to get Bilstein B8s is there a similar alternative from Koni or such that works good with lowered setup? I'm considering coilovers as an option too. Seem like BC or Broadway options might be similar cost to the H&R / Bilstein B8 setup. I know KWs are great but more than I want to spend.

Thanks in advance!
