The springs haven’t settled yet, and if they settle 5mm’s or so it would be just perfect.

The front drop with a front lip is what has me concerned. I haven't installed either yet - have you run into any issues?

No issues, but it is lower by almost 2” in spots

A couple people asked about the special tools I used. All Amazon: 18mm strut socket, strut spreader sockets (need 2), spring compressors.


ZKTOOL 080 Suspension Strut Socket Tool (18mm/12PT) VM #:3353, 1/2" DR. x 18mm, 12PT. https://a.co/d/dPALfon

ATLIN Strut Spreader Tool – Strut Socket for Audi, VW, BMW, Mini, Ford https://a.co/d/e09uu8r

OMT Spring Compressor, 11-1/2" Macpherson Strut Spring Compressor 13/16" Socket 1/2" Drive to Compress The Coil Spring, Set of 2 https://a.co/d/ef49KAg


You will also need a 16mm socket and 16mm offset box end, and a 16mm crow foot might help, but not necessary. I mention this as my tool sets had 15mm and 17mm, had to get 16mm separately.

any update on cost of oem struts and work?

[fanofbmwe46]

Anyone else have a strut go bad already from using these? Sounds like there is at least one report of struts leaking.

Most suspension components seem to normally last 10yrs/100k miles before items start to need replaced at least based on my experience with many stock BMWs in the past. What’s the consensus on decreased lifetime of suspension with a set of 20mm lowering springs… 5yrs/50k miles? +/- ?

In response to your pm, I may as well answer your question here to help everyone else.

The ride quality on my car is still the same, no issue. I’ve driven the car around 2k miles since install. I’ve had Eibach springs on factory struts on previous cars and never had any issue during ownership.

Is there a difference between ride heights of xdrive and RWD? I just installed a set of eibach pros on my G82 xdrive and the rear was way too high when I only had the fronts on. I immediately added the rears to give it a consistent height across the whole car. Prior to doing that, I was worried that the 20/20 mm drop would make the rear too low.

any one move to Eibach from H&R? Trying to weigh the Eibach springs vs H&R Sport springs. I know the H&R's are bit lower.

They’re similar design so the feeling will be the same. I’d guess the h&r are a touch stiffer to compensate for higher chance of bottoming out.

I’d buy based on the ride height you want.

Just recently had a KW HAS installed on my 23 m3 comp xdrive. The car is basically new less than 700 miles. I was driving the car normally and took a slight hard left turn and noticed what seemed like slipping and bouncing of the wheel. As I turned the steering, i kept feeling like i was loosing control and the car was slipping as I was turning.

So took it into the shop, they say its a blown right front strut. Im just confused if this is normal or if this is a shop install error or what could have happened? Thanks

Hmm that seems very odd. I’m not an expert on this but I’ve read many posts about lowering and you might be only the 3rd in here that has reported a blown shock.

[cubanbimmer3]

I have decided to write out some rough math (all estimates given labor costs) to compare the cost of MP HAS vs Eibach front only springs, which I believe several of us are comparing.

1. MP HAS installed at port $2800 + $300 to adjust the springs to desired height (I feel the front needs more drop and the back needs less from factory settings)+ 250 for alignment = $3350.
2. MP HAS delivered to home $1800 + $1400 installed at reputable shop including alignment = $3200.
3. Eibach front only springs $260 + installation/alignment $500 = $760.

I am curious to know how much it would be to replace a blown strut out of pocket. If it’s going to be $2000, then MP HAS seems like a no brainer given that would roughly cover the cost delta compared to the Eibachs.

Personally, front springs are all I need. I think the back looks great stock, and do not need a HAS kit (no plan on tracking). I am however concerned that blown struts are seeming to be a bit more common.

Option 1 seems to be the least logical in the sense of time given that the car will be delayed at port, and I would still need to take the car in to be adjusted/aligned, but factory warranty would be maintained.

Option 2 could be an issue with warranty given that it would not be installed at a BMW dealer, although this could be fought.

Anyone else in the same boat/have any thoughts on this? How much is it to replace a blown strut? If you do blow a strut w/ front only springs, are you going back to stock?

front shocks are about 7-900 depending on where you order from.
https://www.getbmwparts.com/oem-part...ut-31318091349

I'm about 600 in on springs+install+alignment.

I did the math and I did not feel like spending 3-4k on BMW's HAS + dealer install on the off chance that something maybe might happen that never has on any other car I've ever lowered.

I've seen 3 blown shocks on the forum (there could be more) One was Eibach, and they complained about rattling loose noises after install, before the shock blew. That points to an install issue to me. The two others were KW (essentially the same kit as BMW) and one blew within 10 miles of driving, which sounds like the installer screwed up to me, too.

with the hundreds of G8X cars being lowered without issue that don't come in and comment, and my past experiences lowering cars conservatively with no issue, I'm not concerned about the very mild Eibach drop hurting the car. At least not enough to shell out 4k for an OEM kit to achieve the same look I wanted.

The MP HAS kit is $2820 installed at port, not $4k. Still more than just springs + install & alignment obviously, but just saying. I chose the MP HAS kit just to not have to worry about possibly getting a bad installer or warranty headaches down the road. Plus I looked at it at just another option checked on my build sheet and it’s part of the loan.

[Team Tonka]

I'm one of them with Eibach and blown front struts. Basically, just to get new struts your going to be around $1600-1700 shipped to your door.

I'd do option #1 above because dealers (or the local BMW rep. can decline based on the weather - and your effed).

I've watched several videos and read how BMW wants them installed, still can't see how anyone could mess up the install. I'm blaming faulty struts.

[cubanbimmer3]

My dealer told me that I cannot add on the MP HAS kit now that my car is in production. I was surprised, given that it would be a port-added part, and my car is still in Germany.

[fanofbmwe46]

Wow last few posts have read my mind and perfectly summed up what I’ve been debating.

The kicker is my dealer said any adjustment to the MP HAS from the recommended 10mm drop all around essentially voids the entire suspension warranty. Emailed BMW genius and they said it’s dealer discretion. So that totally turned me off from MP HAS although I have to believe it could be argued and won or the kit could be simply readjusted to 10mm drop if something went wrong and then brought into dealer.

I ended up ordering Eibach front springs because I plan to only put 4-5k miles on the car a year and highly doubt I’ll have any issues (maybe 1-2% chance per year of a blown strut?). The savings is self insurance toward new struts and install ($1700 parts and probably $600 labor to install two new ones).

My car is still waiting in Germany for a boat. Pretty sure MP HAS can be added to the order anytime before it arrives.

If I don’t do it at port I probably won’t have it done at all. Dealer labor quotes I’ve gotten to install after delivery are $2200+ just for labor.

Pretty sure this came up in another thread before, I think the actual MP HAS kit one. You should be able to add port added options until it arrives at port in the US. I’d have them double check.

I ordered the Eibach springs a few months ago but chickened out and sold em after hearing these stories of many blowing their struts, also multiple stories on FB, too. Ended up w just 13mm spacers all around and the gap doesn’t look as bad anymore.

Looks good. I think only 1-2 reported blown struts. And I have researched this in depth.

Do you have any more side profile shots? Any rubbing?

Don’t have many pics since I just installed em yesterday. No rubbing. Here’s another one I got, though.

[dmand]

I couldn't be happier with the Eibach front lowering springs ("leveling kit" as I call it). Then the spacers just set it off...
