Does anyone know the best place to get some Bilstein b4s dampers?

Demon Tweeks seem to have the best prices on these currently. Check their website or the Ebay shop.

I got mine from TDC Automotive on Ebay

I found the B4's were stiffer than OEM sports shocks based on running them on my E46. I therefore went it OEM Sachs on my E90.

I believe the B4 (sport suspension variants) are also shorter than OEM?

The B4S are designed to work best with upgraded springs such as Eibach.

Paired with a set of eibach pros is the plan.

I did have a b12 pro kit on my e87, but IMO it improved the crashyness but was a bit too firm for the crap UK roads. So I think the B8 shocks that it comes with would be too hard for an e91.

So I would imagine that the b4s would be the middle ground? and with a bit of luck a bit cheaper as well.

I've just replaced the standard M Sport shocks for B4's on my E91 and the shocks were the same length however as my old shocks were knackered the car sits a little higher now.
The ride quality isn't any stiffer but its a million times better on the road to drive.

Interesting. What are the Bilstein part numbers?

[richk84]

Remember there are two versions of the B4 damper - normal and sport

These are the Sports part numbers -

22-135032
22-135049
19-135052

Mine is pre-LCI although not sure if that makes any difference.

According to Demon Tweaks those are the correct part numbers for a 3.0 Petrol with sports suspension.

I've just bought b4s of tdc automotive on eBay, eibach springs from a German company on eBay and all new bumpstops/ spring pads etc top to bottom from Cotswold BMW.

Just waiting for time to fit it

I have fitted B4/Eibach on the front of my SE after I suffered a spring failure. Very happy with the rideheight and the ride quality. Matching rears going on soon.
