B12 is b6 with eibachs. You saying eibach Springs are back ordered?

All that said, fresh Sachs on an otherwise fresh factory setup is quite plush and still handles very good. So it depends on if you want max comfort or more of an edge.

In between these two options sits the Koni/Dinan setup. Less aggressive than B12 but more sporty than stock....same drop as B12....ish.

+1.

Also if you already have the B6 damper, why not just order the springs from Eibach?

I have the B6 HD's. I thought the B12's with Eibachs were the lowered springs with different sturts/shocks to accomodate the slightly lowered stance? Are the struts and shocks really the same between the two??

The B12 Kit consists of Bilstein’s B6 damper and Eibach Pro Kit lowering springs.

However I believe it was revised a few years back as it was initially sold with H&R springs.

From the Bilstien website:

"This BILSTEIN B12 kits consist of BILSTEIN B8 high-performance shock absorbers that are perfectly matched with EIBACH springs for an optimal ride."

https://www.bilstein.com/us/en/produ...n-b12-pro-kit/

https://www.bilstein.com/uploads/tx_...6_b8_en_35.pdf

BILSTEIN B6

Performance you can feel.
If you expect more damping power from your shock ab-
sorber – even under loads – but don’t want to opt for an
all-out sports model, the BILSTEIN B6 is the ideal solution.


BILSTEIN B8

Shortened high-performance shock absorbers
for virtually every lowering spring set and series
production sport vehicles

Should be B8's with Eibachs. I tried Bimmerworld and Amazon, didn't try anywhere else. BW told me it could be 6 months before they are in. My Amazon order says not to expect them till mid Feb, and I placed the order back in Nov.

Bilstein did not make B8 dampers for the E46 M3.

As previously said B12 Kit for E46 M3 = B6 dampers + Eibach springs.

The b12 are b6s. The b8s were for the none M as stated above.
I haven't driven on those with eibachs. But on vogtlands with the bump stops shortened, they are out of this world better. Like you wouldn't believe the difference it makes. Super super planted. U can keep ur foot in it in corners. Like 10 times more grip I kid u not.
