I bought the correct eibach springs from Tunershop. Super fast shipping and a competitive price. Unfortunately, I failed at finding shocks. Tried buying B8's, then FSD, now I'm on hold until after the kids get dropped at colleges at the end of the month. I did consider buying the B12 kit from them, but I was skeptical that it was in stock.

Same concern here and I exchanged a few emails with them to make sure the B12 kit was in stock prior to ordering. Alexander at Tunershop was very responsive and even sent me a note to confirm the items shipped.

I strongly considered the FSD route and still think it is a really good option. They were not available for a while during the transition to the new style Special Active but should be in stock now. BTW I called Koni and the only difference between the new and old version is the name and paint color, the tech inside did not change.

Bummer, sorry to hear that.

I struggle to understand how Bilstein can essentially abandon the enthusiast market for almost a year now. More confusing is that they are still advertising in various publications as if all is normal. At least there are some strong alternatives.

I cancelled my Bilstein order. No idea whats going on with those guys.

I genuinely don't know. This has been going on for nearly a year now. I've sent a message up to them to see if there is any light at the end of the tunnel.

Probably for the best, let me know if anything else interest you.

Thanks again Jeff, for setting me up with the KW order. Excited to get off of this awful xi suspension.

I'm still rocking the Bilstein B8s and Eibachs, and still love them.

Had two replaced under warranty (Bilstein's lifetime warranty is awesome) 18 mos ago. Car still feels great - perfect balance for me.

Instead of using B8, I was always curious to know if Bilstein B4 Sports would work on an XI.

[Herakles]

Can someone post a refresher - on what bilsteinb4vs b8 (stock vs lowering spring application)

[sparkyblue]

This may sound silly on a BMW forum, but I use my 335xi as a snow-car and DD. Thus I can't lower the suspension as installing chains would be a pain.

Which Bilsteins should I replace the old and aging stock struts/shocks with?

I was only missing a Bilstein B4S right struct 22-136619 to complete my setup for installation. 3 vendors sent me Sachs OEM strut lol. Trying for a 4th time; buying from an independent seller who confirmed he has one more Bilstein 22-136619 in stock.

Mine is my DD as well.

I am trying Bilstein B4 Sports all around (all the hardware, bump stops and mounts for sport suspension as well) along with Eibach Prokit 2092.140.

I heard they've been completely revamping their north american distribution, including all new warehouse locations etc.

Still happy with this? Any pics? I like the idea of the minimal drop

Yes very satisfied but keep in mind when I say minimal, I mean just that. You couldn't tell if the car had aftermarket springs. It looks more like what a factory sports package, basically how the car should've looked day 1. The only reason you might be able to tell is because relative to the fronts, the rears take on more drop. This isn't surprising considering Dinan themselves only offers (or used to) shocks for the rear. The fronts aren't intended to be slammed on the Xi but if the wheel gap really bothered you, I suppose you could run a 235/40. Fronts would be fine, rears should clear...

Car handles great and more importantly is very comfortable. If you wanted to eek out a little more handling, the Dinan fixed camber plates would be a nice touch.

See my virtual garage to see how the E90 looks. For comparison, the 135is was Dinan springs, BMW Performance shocks and the 07 Z4 was riding on TCK D/As.

[3002 tii]

FYI not sure how accurate their inventory is on their site but Turner has the B6's for Xi available. Definitely firmer than the B4's but assuming you already ditched the runflats, these would pair nicely with the Dinan springs since B6's are intended for factory springs and Dinan is so conservative to begin with.

And just remember when you do your suspension, replace/inspect all the ancillary parts (strut mount, rear shock mounts, FCAB, RTAB, sway bar bushings, etc.). I ended up replacing mine with all OEM stuff from FCP (warranty for life even on wear n tear parts).

I'll second this excellent advice.

Just did springs and dampers on my E91 Xi and refreshed all of the front suspension at the same time. In the rear I just replaced the upper and lower shock mounts - the rest of the rear was still tight.

At a minimum in the front I would replace the upper strut mounts and rear most front control arm (traction strut in BMW speak) and rear shock mounts. The traction strut bushing looked decent however once removed it was obviously worn. I had a *touch* of shimmy when initially applying the brakes that is now gone.

For the record - I installed a B12 kit specific to the E91 xi (B8 dampers/Eibach springs). There is minimal drop (~about a 1/2" all around - it might settle a bit more) and the responsiveness is worlds better than the 80k stock setup while not being harsh. I was attracted to this kit since it was a matched set, included proper bump-stops front (internal)/rear and did not slam the car to the ground. This has been the second best modification to the car - the first being replacing the run-flats with "real" tires.

Well, the Bilstein B4 Sport struts with corresponding strut mounts did not fit my xDrive model. Longer and thicker at the knuckle than the B4 Standards. I should have known better but at least I know now.

The Bilstein B4 Sport shocks would fit though (which wasn't a surprise).

[BeaterM3]

Does anyone have an idea as to any adverse consequences with running B4 Standards in the front with B4 Sports in the rear paired with Eibach Pros?

Probably worse ride and decreased life of the standard B4 since they weren't designed for lowering springs.

That's a bummer. I have read someone on here that it was acceptable to pair Eibach Pros with B4 Standards, as long as the drop is no more than 30mm. The fronts on mine are 25.4mm and the rears are 20.32.

Blurred lines this.

In short you can use both.

The standard B4 can be used with se springs, m sport springs or any lowering springs up to 30mm

B4 sports are shorter so require a shorter spring. Off the top of my head I think m sport and up to 50mm lowering springs are okay, but no SE springs.

I would say b4 sports for replacing m sport shocks, unless you want a more comfort in which case the standard b4s.

I had to go with Standards in the front and Sports in the rear with Eibachs for the time being to at least be able to drive. I will most likely just return the Sports to FCP and replace them with Standards just to be similar all around.

Besides rubbing like a mother in the back because of the drop and my 265s, the ride seems fine so far. I am pulling off the 265s and throwing on Style 340s for the winter, so I won't be dealing with and rectifying the rubbing again until the spring at least.

[BeaterM3]

So after pulling off the 17x9 245/45s from the front and the 17x9 275/40s from the rear and threw on my 17x8 225/40 square winter wheels, obviously no more rubbing in the rear and the ride is freaking great. I will have to get my rear fenders rolled and my fender liner modified come Springtime in order to run the other wheels.

The stance looks pretty damn good for an xDrive without coilovers.

I am going to run this set up for a bit and see how the ride feels after a few months.

What I installed - Bilstein B4 Standards in the front and Bilstein B4 Sports in the rear with Eibach Pros 2092.140
