I'm in the US and really want to lower my car. It's the 2023 BMW i4 eDrive40 with MSport package.
I'm looking at Eibach E10-20-053-01-20 and wondering if this would work if my car came with Adaptive M Suspension.
I purchase this car from a canceled order and under features and options lists Adaptive M Suspension.
Bummer... My prior car was much lower than the pictures shown for the Eibach lowering kit for the i4, and yes it can be annoying to drive/maneuver steep driveways and bumps/humps (But I let my front lip take all the damage)...
However, this car just sits way too high in my opinion... (maybe I was too used to my prior F30, with a finger gap between tire and fender)
Yep, that's all!
Dropped the car about an inch. Rear links will need to be adjusted accordingly to match front drop. (front wheel will have slight negative camber, but really unnoticeable)
Makes the car look more OEM + (I can barely fit 2 fingers between the gap now, instead of like 4)
And, already scrapped my aftermarket front lip... but the springs were worth it!
When you lower the vehicle, the lights should be adjusted according to a previous post here and a friend of mine who is a mechanic for them. I guess the lights cover a certain range based off the factory angle they’re set at. So lowering the car lowers the angle so your lights point lower.
I have not researched this though. This is my deduction from the conversation I had with him and from what I remember about a post on here. If someone here is more accurate, please enlighten us both.
$300 sounds too good to be true. Almost untrustworthy. But at least you got a huge deal
Yea, he was the cheapest and had done couple of i4's, so I just took it to him. Basically just him in a small shop so I guess there wasn't much overhead cost there.
and...Got it! I didn't think of factoring in headlight adjustment. The guy matched the rear drop as exactly with the front springs drop, measuring constantly with a ruler, so I just assumed I didn't have to adjust my headlights because there shouldn't really be a change in angle.
I'll go check my headlights against my garage door today, I may actually need to get them adjusted after alignment. Thanks for the tip.
Well, that ain't an option for me so I'll hold off until some other people get the car lowered successfully with adaptive suspension. Keep us updated if all stays well with the springs!
Just curious, what issues would lowering 3/4 to 1 inch thru springs and smaller links cause on the dampening system?
Plus our cars are EDC, so it's electronically controlled.
I wouldn't worry about it, the springs and dampening system aren't even connected, more parallel each other.
What would be considered a successful lowering kit, if that kit still only comes with spring and links?
@Don Juan successfully installed on his e40 MSport so I just went with it, since it was such a great value @ less than $300 from that site (<$300 vs >$1000 for coilover kit for barely 1 inch drop). Assumed setup should be similar to m50 w/ adaptive. @Techwhiz1 seems to have installed successfully for his m50 w/ adaptive, so I'm pretty sure it will be fine for you as well, if you're still on the fence.
My understanding is that the M Adaptive Suspension is the electronic dampening system for the BMW, that has been for years. It's what helps dampens and softens your ride in comfort mode. Either you have it or not, just 2 options...
With that said... when installing this kit, I still feel the difference from changing from Sport to Comfort mode. I doubt the kit will cause pre-mature wear and tear on the dampening system...but I'm no expert as well...
Here is a 2020 article regarding the Adaptive M Suspension
Precision creates emotion: driving pleasure is the DNA of every M model. Many components and technologies contribute to this and one of the most significant is the Adaptive BMW M Suspension. Why? Here’s the reason.

States they are Electronically controlled shock absorbers
Hi, Just comming from an F30, and I kind of miss having a PSM style spoiler. Are there any aftermarket PSM style gloss black rear spoiler for the 2023 BMW i4 eDrive40 in M-sport? Or any in ebay that may fit this trunk? Any help would be appreciated Thank you!
It's roughly less than an inch drop, the stiffness is there but the difference is not by much. I can feel the roughness on the freeway a bit more than before on Sport mode, but changing back to comfort pretty much dulls that pretty good. Basically, you won't feel a huge change in stiffness, I didn't. (i'm on 19's with 10mm rear and 13mm front).
I try to avoid anything steep for I also have an aftermarket lip installed, and I also take precautions on bumps (slowing down and approaching bumps at an angle)
However, the downside is now all your tires will be at a negative camber. Be prepared to change your tires sooner then expected, re-alignment doesn't help that much.
Here's my alignment for i4 eDrive40 Msport
Most is considered "within spec" but the right front camber was just a slight negative out of spec... but .03ish difference on each side on the front isnt something that will bother me alarmingly. I'll just buy different set of tires next time, which will be stated to have more life compared to the Pirellis
