Good job on the install T. Enjoy in good health.

If you did make a DIY video of the install, let me know. I'll edit it in on the first post of this thread and the Suspension Master List thread.

Has anyone made the jump from Eibach to MP HAS? If so, can you comment on how they compare, particularly in regards to ride quality?

I'm sure this has been asked before but it's a 108 page thread. Anyway, what is BMWs recommended lowering height and how long did you guys wait till you got balancing and alignment done after installation?
Thanks in advance

Check the install instructions.

It's a 25mm drop from stock I believe.

Instructions are on getbmwparts

Thanks. I just ordered it last week and waiting for it to arrive. I'll check if it comes with instructions and if not I'll check the website.

Both of them are great with pricing and will offer free shipping. If you live outside of their state then you don't get charged for tax

Same bro.

Mine arrives this week.

Gonna have it aligned on install, then do a more aggressive track alignment a week later.

Well I had a chance to install the kit today....wow boys and girls, this is the kit to have! Well worth every penny. I told myself when I bought my car that I wasn't going to touch the suspension (knew that wouldn't last), but wanted to lower the kit with something engineered for the car. At least so far, boy did it deliver.

The install kicked my ass - not because it was hard, but just because I dragged it out due to my extreme caution. I've been wrenching on cars for 20 years and I've never been so careful with suspension work. Even knowing what to look out for, I accidentally banged the sensors a few times, but no codes.

About the ride and handling - wow these things ride great. If the stock setup is a 5/10 in firmness, I would put these at a 6/10, but it is very controlled and compliant. I was really worried about the "lowered ride" of some spring setups, but this ain't it. Thrilled with the ride. Handling is obviously improved greatly, body roll diminished even in comfort mode. As a result, some of the numbness if the steering is gone too. As a bonus - my occasional strut clunk in the front end seems to be gone (I have this one stretch of road where I can make it clunk every time).

I set the ride height arbitrarily based on Tommy's video. Might have gone too low - measures about 26" from ground to fender on all corners - did I slam it a little too much? Might raise it up a little. The only weird part is the left front had to be adjusted down further than the right front to achieve the same height.

I'm going to drive it a few days to get the ride height dialed in, then send it in for alignment.

Looks great. I also had to lower one side more than the other to get the right heights, but it was within the recommended less than 5mm difference so did not worry about it. I have already tracked the car once and it did great. Enjoy.

The right way of doing this is, after setting the desired ride height, to put the car on scales and fine tune the height until both diagonal weight sums are the same. This is called corner balancing and ensures balanced cornering in both directions.

This is timely. I have the BMW HAS installed on my 2016 M3 and was just discussing corner balancing with a friend who knows much more than me about this. He said:

"I assume the corner weighting was done with you in the car and the suspension settled and the anti-roll bars (ARB) disconnected, and then reconnected at the corner-weighted heights. If they didnít have the anti-roll bars disconnected, the report can be misleading. If you donít have adjustable turnbuckles for the ARB attachments, there is nothing they can do about it."

And...

"Do you have aftermarket anti-roll bars? If so, most have different hole positions to adjust the stiffness and the link that attaches to the hole has an adjustable length. When you make corner weight adjustments you change the ride height at one or more corners. If at least one side isnít disconnected on the ARB, it torques the ARB and artificially changes the corner weight. One side should be disconnected on both the front and rear while making the ride height changes and then reinstalled with no load/interference when done at the new ride height."

I do not have aftermarket ARBs.

Can a proper corner balancing be done on my M3?

I agree with this 100%, next on the list and likely camber plates to further adjustability.

Had a chance to set my ride height - been tweaking all week. This is not a process for someone who is OCD like me. I got all 4 within 1/8" of the BMW recommended settings. I'm pretty happy with the way it sits and rides, so I sent it off for an alignment.

A few notes on adjusting the rears after installation - basically this area is the one lone engineering defect of the kit. The rears simply cannot be adjusted after the fact with the included wrench, there isn't enough stroke because the shock and the wheel well lining get in the way. I improvised by using a Channelock oil filter wrench with the teeth wrapped in electrical tape to lessen the marring of the aluminum. This worked pretty well but did not stop the marring completely, but didn't have a choice other than to remove the lower control arm bolt, which I did not want to mess with.

Knowing that the top spring seat spins rather easily, I put 3M tape (VHB) on during installation and that seems to have worked great at keeping it still when adjusting the collar. I sprayed the threads down with WD40 and it was very easy to turn. I also jacked up one tire at a time rather than the whole rear end while making adjustments. This seems to put enough resistance on the spring (via sway bar) to keep everything in place except what you want to turn (the spring collar).

The fronts are cake to adjust. I added a heavy dab of anti-seize to the tiny set collar, hopefully that's enough for removal if I want to make adjustments down the line. IMO this set collar is awfully small so we will see.

The car drives straight just as it did before, so hopefully the alignment shop won't have any issues getting the specs back in line. Visually, the camber doesn't look as bad as I thought it would, but I can see a difference in toe.

Next up are some 10/12mm spacers.

Seems high, but not uncommon. Dealers in my area are anywhere from $750 up to over $1500. I recommend making sure they've done the install before... there are stories earlier in this thread about dealers installing things incorrectly.

A bit high but not by much. I was the first install on my dealership in Virginia. They charged me just over $1200 but they had such a problem installing the kit (don't ask me why) that the next customer who tried to get them installed was quoted $1800.
