Ok noted.

Let me rephrase - perhaps not add any advantage by doing front springs only but rather keep the OEM characteristics intact while still getting the benefit of improved looks via front end lowering. Essentially, this may lead to OEM ride characteristics remaining the same for those that did not wish to change the ride/handling but only wanted a slight front end drop for visual appeal.

What is ur view point on the spring rates, as you eibach is marginally lower than stock CP rates, will that be noticeable

Wouldn't worry about it. It's a spring. Give it a year and it'll be chipped up, dirty, maybe a little rust. Take note of the stockers condition when you swap the Eibachs in, you'll see what I mean.

Here's some more V2 pics.
2016 non-zcp
stock 255/275 tires
Turner 12.5 mm spacers front & rear

For reference front camber came out to -1.6 on both sides. Car def rides stiffer than stock, but not terrible. For a daily not sure how anyone would really want it lower.

35%

I don't like them any darker. I think it's Johnson film.

Cheapest I found these is ModBargins.com for $261.63. You think that is legit? Sounds kind low compared to what i have seen. $327 was the next cheapest.

That's legit. I got them for $250 a while back from a reputable SoCal shop.

Thanks! I went a little further in the checkout process and once you select springs for a specific model it adds another $65 bringing total to $327 plus $29 for shipping Misleading. Wont buy from them.

EAS doesn't carry these. IND doesn't carry these. Supreme Power doesn't carry these. Are the springs off the market and only Eibach themselves stocks any? What's the deal?

They seemed appealing because of the moderate drop (Houston has the worst roads and curbs in the country) but am I better off getting Macht Schnell or Swift, even though they drop more?

Have to search by the correct year on some sites (2015, for example, though my car is an '18). Just....odd.

E10-20-037-01-22 also seems to be the code for the M4 on Eibach's site. Hope that's correct, since it doesn't match the discussions in this thread (which were M3 related, predominately, I think).

I have them with ZCP coding on non-zcp. Rear rebound is terrible in comfort, so so in Sport (not enough rebound damping on bigger bumps IMO). Sport+ is great though. I prefer driving on the street with the Sport damping though.

Been trying to get Alex to code the CS damping and some other things but it hasn't happened yet. Will report back when I can get it done.

Is there a difference in drop between competition and none? The competition back is already perfect but front it still needs a drop..

Competition and regular M3/4 have the same ride height.

I find that aesthetically the M3 needs less drop in the rear than the M4 due to the shape of the fenders.

I hope this is version 2? E10-20-031-09-22

Seems like Europe the partnr is still the same.. There are almost finished. I don’t hope that rear will be higher right now... Because back was perfect, only front needed a drop..
