All,

Good afternoon! I have been doing a ton of reading on lowering springs for my 16 435i xdrive gran coupe. From what I have learned there is limited options for me.

I am really just looking for it to be the same height as the non xdrive. One thing that I could never find out is, can I take the oem 435i grand coupe non xdrive springs and install them on my car? Will that give me the desired height and still maintain ride quality?

Otherwise I think the Eibach's will be the best bet for me as they are a minimal drop and only 10% stiffer.

Thanks!
Dereck

Does your vehicle have M Adaptive suspension?

Well that's a good question. They said it did but when I used the VIN decoder I did not see it listed.

Thoughts?

Bump.

After thoroughly reading through this suspension forum, I pulled the trigger on a set of Eibach Pro-Kit E10-20-031-18-22 springs for my 2019 440i Coupe xDrive with adaptive suspension. In a nutshell, these can use the the existing "Adaptive" shocks and stock "Bump Stops". These Eibach springs bring the xDrive close to the "Sport Suspension" height. With only springs to change, the swap seems fairly simple. From my understanding, the BMW suspensions are as follows:

• 0 MM - Standard Suspension 0 MM
• -10MM - Sport 704 Suspension (RWD Only) is lower from standard
• +10MM - xDrive Suspension is higher from standard

Sport suspension is ONLY found on RWD Sport and RWD M-Sport models! The xDrive DOES NOT get lower the Sport 704 suspension, ALL xDrive models get same springs regardless of model! Therefore by my above calculations, ALL xDrive models are 10MM higher than the standard and 20MM higher than the RWD Sport 704 suspension (20MM = 0.8"). The Eibach is 0.8" Front / 0.4" rear which is very close alignment of RWD 704 Suspension Height. The xDrive & RWD use the same Bump Stop and with Adaptive Shocks, these springs do not require any change for this upgrade. However, standard shocks should be changed from what I have read in these forums.

The issue with swapping for the 704 Springs is these may not be strong enough for that additional suspension weight of xDrive in addition to the added front weight (over 100 lbs all in the front). I was unable to locate any spring pressure data to evaluate so it would be a risk.

I have two quotes so far to change out springs, looks like about 6.8 hours is the estimated time to perform. Both quotes I have are in alignment at about $570 for both Front & Rear springs to be swapped. I am trying to locate a good guide so if I was to swap these out on my own, which seems pretty strait-forward, my challenge, the biggest issue, is locating the proper torque values for reassembly.

Although these individuals did not post here, I want thank FaRKle! and johnung throughout this forum for all the great input on suspensions. I know some others have great input also, but they answered so many members questions and made this so much easier to find answers to any questions I had.

I will post before and after pictures yet I may not perform the actual change for several weeks.

Does the 6.8hr time quote include alignment? Swapping just the springs on F2x/F3x should actually take much less than that (more like 3.5-4.5hrs). If it does include an alignment, then it means the alignment portion is costing about $200 (back calculating from your $570/6.8hrs quote).

It does not include the Alignment.
I just put the cost of swapping springs, again I thank you for the input you have provided throughout the forums, it made the decision easier with the information to make a good choice.

Hello,

Like Der2z I also have been combing through these message threads for research on lowering springs. I have a 2019 440ix GC with a huge amount of space between the wheel and the fenders.

I totally appreciate the usual suspects providing a wealth of knowledge and experience here to many of us.

I've narrowed it down to a set of Eibach springs due to the stiffness and mild drop; however, I need some help narrowing it down to which set.

I originally though it was going to be the E10-20-031-05-22, as per the Eibach European site...but can't seem to find them for sale anywhere in North America. My local shop is recommending a set of E10-20-031-18-22 which don't really indicate they are for the 440ix GC.

I also see members using E10-20-031-06-22 or 02-22.

I need some expert advice on which set would work the best for me.

Thanks in advance.

Hello!

From my research the 6-22 will lower it .8 inches in the front and .6 inches in the back.

The 5-22 will lower it a little more similar to the H&r springs.

I think I'm going with the 6-22 set with koni reds. Koni does not list a set of red shocks and struts for a 435 or 440 xDrive but Farkle told me the ones for the 335i xdrive will work.

They offer the yellow Konis but they are stiffer than the reds.

Hope that helps a little.

Thanks Derek,

Got any before and after pics?

From your profile pic...we running the same car are well as the exact same wheels.

No problem!

I haven't lowered mine yet. Still deciding on if and what I want to do.

[smak168]

just checking...kpgrey indicated:

0 MM - Standard Suspension 0 MM
-10MM - Sport 704 Suspension (RWD Only) is lower from standard
+10MM - xDrive Suspension is higher from standard

So when Eibach indicates a 0.8" drop...for an Xdrive, it would actually drop the car the 0.8" + 10mm?

0.8" equals 20mm...so the total drop would be 28mm? Same as 1.1"?

Thanks

Great question.

From my understanding the drop is a true .8 and .6 drop with their 6-22.

The 5-22 springs would be the .8 and .6 plus 10mm give or take.

So my car is the 15 f32x coupe not gran coupe but its an N55 so we may have the same weight specs. I just lowered my f32 on Dinan Sport lowering Springs (also bought the bump stops from Dinan aka "ride quality & handling kit"). They advertise .75" in the front and 1" in the back plus 30% stiffer ride, I must say as far as the height go's its pretty spot on to what they advertise, it may be even slightly more than .75" in the front.

I'm pretty pleased with the results especially because that god awful xdrive wheel gap is gone and it doesn't look like an overdone slammed car either, I also forgot to mention im on stock shocks and struts, Dinan said these springs were meant for the OEM shocks.

as far as the stiffer rider is concerned, tbh i dont really notice much of a difference its subtle and perfect for DD even when you hit bumps you can tell its stiffer but not nearly as harsh as my friends e92 on h&r super sports.

Der2z...any pics yet?
