I'll be working on the car this weekend because the front is still a half inch higher than the back. My plan as of right now is to remove the bumpstops, measure the fender to ground clearance, modify either the M3 or Original bumpstops, and then reinstall.

Here's a picture.

Have you tried M Performance bumpstops? Guess they might be very similar in size to the M3 ones. I have heard that the Bilstein Shocks have very high gas pressure to greatly reduce cavitation and can make the height higher than OEM. Also I noticed from the following picture that the spring cup on the Bilsteins sit higher and or don't taper down as much as OEM.



Personally I like how your car looks, I'm not a fan the raked look, so your flat stance looks good to me. Hope you get it sorted!

Bumpstops are off, waiting to see if the car drops any over night. Right now I have about a 1/4" rake on the drivers side, but about a 1" rake on the passenger. Side to side the front passenger side sits about 3/8th of an inch higher, however the passenger rear sits about 3/8ths of an inch lower.

That's a good point. I remember when I put B6 based dampers on my car, even though the gas pressure was reduced to the minimum needed to prevent hysteresis my ride height increased like 0.5" all around.

That said, the damptronic models aren't monotubes, so they shouldn't have the typical Bilstein high gas pressure.

Yes correct they are twin tube, much to my surprise when i called Bilstein directly about this. Previously assumed they were mono tube as the passives are mono.

One of the hints that it's a twin or triple tube is the solenoid valve is on the side. The wire connects to the extra side protrusion. The monotube F8x EDC dampers have the wire going through the top of the piston shaft.

Matthewricha it would seem that is the cause of the front raising. I'll be reinstalling the M3 bumpstops this morning with no modifications. The front ride height is the same as yesterday after sitting all night.

This exploration was due to being able to turn the wheel enough to fit my hand all the way back to feel the M3 bumpstop at the top of the damper.

Guess my next step is to buy and install a different set of springs that won't lower the rear of the car as much as the front.

Alternatively you can make some spacer/shims to put into the rear upper spring cups (on top of the rubber spring pad) to shim/raise the rear ride height. This is what Macht Schnell does for their F8x spring kit to correct the rear ride height so they can use the same spring for all F8x's (BMW has different springs depending on if the car was optioned with a sunroof or not).

I used this method with my own car since there weren't any springs I found with the spring rate I wanted that were the right length. I used 0.1" thick Kydex to make my shims and am running multiple of them in the rear cups. For 0.5" at the wheel you'd want 1-2 0.1" shims in there. The first shim should be 85mm in diameter, to account for the taper in the cup, but after that can be 90mm.

FaRKle!, I will have to keep this in mind. It's going to be a few weeks until I do anything else at this point.

Here's a pic of my spacers. I have two on the top of the spring cup (had to cut a hole in the middle for the spring cup post) and 3 inside the spring cup.

This will also applies to RWD cars? Front dampers? (23-250727/23-250734)

Will increase the ride height due the spring cup?

I use prokits with oem dampers and I would like to keep the height that I actually have with this combination. ( I m planning to replace oem dampers with b6 damptronic)

Or in order to keep a similar height should I need to get HR sport that lower just a little bit more than prokits? To compensate.

[DriveS]

I had some B6 Damptronics on order for my 335d. There was supposed to be a production run at the end of June for the rears which have not been available. Its now cancelled and pushed back to the end of August........

The picture I posted was from this site:

so presumably a RWD variant anyway

That article is essentially just an a giant ad, with absolutely no insight to how it changes the driving dynamics.

totally agree!

Found this link at the best price I've see thus far and says September - at least for UK.

I just received Bilstein B6 damptronic
23-250734 and 23-250727

I measured them vs normal struts/shocks(B6 35-264545+)

and there is a little difference between

Shock Absorber BILSTEIN - B6 Performance ->.586m (58.6cm)
Shock Absorber BILSTEIN - B6 Performance (DampTronic®) ->.592m (59.2cm)

and also the position of the swaybar base/mount

not sure if I did it the right way.



here some pics.



For you reference 35-264545+

Now I need to measure vs OEM adaptative shocks or if anyone has this information already? or wait until replace my current OEM adaptative shocks and do the job.

[Eschmacher]

I'd like to see a comparison of the stock EDC shock measurements vs the B6 EDC.

Yes, I'll try to do that.

ha! I came across the same site this morning lol, "Available from September 2019":

question is will it be a proper monotube implementation?

I have also emailed balancemotorsport for confirmation of availability

It's absolutely not a monotube. You can see the solenoid on the side controlling flow into the outer tube. Monotube front strut PNs also typically begin with 35-, so a damptronic version would likely be 36-, not the 23- this is (the twin-tube B4s start with 22- and the B4 damptronic is also 23-). Also, if it were monotube they probably would've done their usual "inverted/upside down" design to increase rigidity.
