Old thread, I know, but I just wanted to update it to say that I ended up going with regular old B4 dampers on OEM sport springs.
I dont have them on the car yet, but once I see how it handles on the OEM springs, I may actually swap the springs with the BMW performance suspension yellow springs if I feel that it needs to be a little stiffer. I heavily expect to find just the feeling of new dampers to be good enough though, mine are definitely totally shot after nearly 100k miles.

If its not undersprung then I will have no reason to change springs. I've just heard that the B4 is slightly stiffer than stock.

It's 10% stiffer, supposedly. But they're still made to match the original springs. If you want to go with stiffer springs, even the sport springs require a different B4 damper. I suspect that would be due to a combination of increased stiffness and slightly lower ride height vs. base stock springs.

Update, after about 6k miles with the B4 struts and shocks they have gone horribly soft. They started out great but of course once broken in they feel much softer and bouncy.
Hindsight is 20/20 but I'm wishing that I would have gone for the B6 or B8 instead. I cant recommend the B4s for anyone unless you are on a super tight budget and just need something to get you by.

I'm not wild about the B4s I put on my X3, to be honest. They're definitely better than the old worn out shocks, but I wouldn't classify them as an upgrade.

Pretty much my exact same thoughts. They work, that's about it. They were cheap though which is nice.

I’m sorry for repeating the same question over and over again but I am totally confused after reading these different examples of suspension . I have a 2012 e92 335i with the M sport package .auto . That’s six speed auto not the other good one. One of the confusing part of this whole thing is when I hear people describe how their stock suspension feels . In my car that I described above has 50,000 miles on it and I would describe this suspension as extremely soft floaty boat like . With extreme body role .This car is dangerous if you load slowly load it up in a turn gently it’ll grab fairly well or ok but if there’s any bump in a high-speed turn you’re just about dead it disrupts the whole chassis . And your all over the place . This side to side transition is horrible. It’s not even predictable because undulation in the road gives you a different or more extreme Chasse disruption . Now as far as luxury the suspension is amazing it floats over the bumps it’s just very pleasant for a luxury car . But for any kind of spirited driveing it’s no good .am I crazy or is that the way the rest of you feel ? And definitely the stock rear dif is horrible omg ! Please tell me the basics set up for spirited street driving or Rare track day . nothing harsh just one good step from the stock msport set up as I have now . Mostly just something that you can enjoy driving the car without feeling like you’re gonna die . Bilstien shocks - dinan springs HR sport springs. And what’s that m3 upgrade part in the front suspension people are replacing . Is that M3 part more heavy duty . Dose it flex Less . Does it have better suspension geometry ?

I'm happy with my Tein S-techs but have to disagree about the drop. I think Bilstein B8s tend to raise cars a bit, so in conjunction with the Teins you ended up with just the right drop. Most including myself (with other dampers) see a 2"+ drop with the S-techs. I hated the drop so much I raised the front back up 19mm via e30 perches and spring pads and it now sits dead even and rides great. I agree that the spring rates are excellent for our cars which is why I chose them, but for most not looking for a significant drop, the Teins would be far too low IMO.

Spring options: (from minimal to extreme lowering) BMW Performance Springs Dinan Springs Eibach Pro kit H&R Sport Swift R-spec Tein S tech H&R Rce Damper options: Bilstein B4 (OE equivalent) Koni Street shocks (non-adjustable but can be paired with lowering springs) Koni Yellow (adjustable) Bilstein Sport Any of the above combinations will work. Be sure to get e36 M3 bumpstops for the front and Z4 for the rear. Or just get coilovers. |

Ultimately these would rock with remote setting functionality, but if they can be set and forget shocks then I'd be happy. |

I think 1.25 turns from full soft in front and 2/3 turn from soft in the rear. I can't imagine needing external adjusters for the rear on a street car. You might have to adjust 1-2 during the life of the shock.

If you're getting bouncy-ness there must be other issues at play here. |

There's nothing wrong, its just that the factory suspension is bouncy, and so are the B4s.
