1. With that in mind, would you still reminded the springs? 2. Why Eibach? 3. Is there a benefit of going with the KW kit you mentioned? 4. Which is better for a comfortable ride? |

Eibach lowers the least, fixes reverse rake because the front lowers more than rear and has the most comfortable spring rate. you can do KW DDC EDC "adaptive" replacement coilovers but they're quite expensive and i'm not sure on the "coding" and stuff. Eibach pro-kit springs with your OEM adaptive will have the most comfort, moreso than most coilovers, even set to the softest setting(except for KW Street Comfort?). here's a link to one of more than a few threads on Eibach Pro-Kit. https://f30.bimmerpost.com/forums/sh....php?t=1901058 the suspension sub-forum has tons of info on the topic for further guidance |

KW are the most comfortable coilovers but wouldn't be as comfortable as the Eibach setup because the KW spring rates are higher. KW Street Comfort spring rates are still higher than Eibach. |

Are these the Bump stops that you are talking about? Front: https://www.turnermotorsport.com/p-2...uine-bmw-part/ Rear: https://www.turnermotorsport.com/p-1...uine-bmw-part/ Are these the correct springs? https://www.ecstuning.com/b-eibach-p...-20-031-18-22/ I'll place the order once I know they are the correct part. johnung I saw you mentioned swaybars in another post, what are the advantages of getting aftermarket ones? How is the handling with the Eibach springs? |

Sway bars control excessive body roll during turns. It's important to do any spring and damper upgrades first and afterwards only change front or rear sway bars if necessary. The labor is expensive on F3x's because a lot of parts need to be removed to access them. I would avoid any hollow bars because they are known to snap. |

18-22 doesn't lower much, 20mm(0.8") front, 10mm(0.4") rear, however some of the gap has been already been reduced by taller tires so this amount of lowering should work out. plus there will be the less stress on x-drive half shafts and minimal to no affect on OEM adaptive damper longevity. if the OP decides he wants it lower than 18-22, there's more research and query necessary to determine the exact alternate kit, imo. |

I use the german eibach parts catalogue recommended by johnung and it recommends the 18-22 kit as well. Seems as if the difference between the F32 & F36 kits are the rear springs. They seem to be slightly longer and rated for a slightly heavier vehicle. F32 440xi: http://web2.carparts-cat.com/default...5&14=15&12=130 F36 440xi: http://web2.carparts-cat.com/default...5&14=15&12=130 Last edited by MTTH; 03-21-2022 at 01:44 PM.. |

Few more pictures after getting it ceramic coated. The wheels look a bit more bronze now.

alohasurftoad & johnung
Thank you for all the advice. I got the springs installed and I really like the look. Barely any body roll but I find the car bounces a lot, especially on the highway and over bumps. Is there anything I can do to reduce that. Will the Koni dampers help or am I wasting my time? |

Eibach is 10% firmer than m-sport springs and even more(%diff) from base springs, since base springs are even softer.
I suspect you are now over sprung, high spring rate with OEM base dampers(slow compression/rebound), causing bounciness. Koni would eliminate the bounce because its comp/reb is more appropriately matched with a higher spring rate. You should have a firm but compliant ride overall, without the bounce. Koni Sport yellow are firmer and rebound adjustable, more performance oriented. Special Active red are non adjustable, slightly cheaper and sporty/street oriented. Either choice is fine and will improve the bouncy ride you have now. Last I checked Koni are 20% off |

https://www.koni-na.com/en-US/NorthA...=555&mk=6&mt=1 I see there are a few options, Is there a one that's compatible with M-Adaptive suspension? Or would I have to get rid of that function? |

2nd option to consider is Bilstein Damptronic which are high performance (adaptive) replacement for your OEM adaptive dampers. this option is not cheap, add labor for install and alignment Koni does not offer an EDC replacement. 3rd option is to replace everything you have now(incl Eibach) with KW EDC coilovers. this is most expensive Edit...4th, as you thought, you can get Koni and code out Adaptive, a few people have done this but most want to try and retain adaptive. .

I am using KW Street Comforts with EDC. I have the height set at its highest setting which lowers the height from stock around 1inch. I have been warned that going lower will induce stress on the sway bar end links. I have purchased adjustable end links just in case this happens.
As far as dampening, I dont feel a difference between the stock suspension and the KWs. Comfort is still cushy and bouncy. Sport stiffens up, but not enough for my liking (xDrive makes a girl fat! lol). Hoping to get under there some time and see if I can make it a little stiffer. I did have these professionally installed by a local shop.

I would research and try the Dinan Shockware to see if you like it as Alohasurftoad suggested Also check that none of your Adaptive dampers are shot. They typically leak fluid when they are bad- at anywhere from 40k to 95k miles. They have to be replaced in pairs. Bilstein B4-Damptronic are close to stock. Bilstein B6-Damptronic are stiffer. Another option is KW EDC coilovers. KW makes excellent coilovers that have well matched springs and dampers Hope this helps |

Did you get these installed? Thoughts? I have taken a similar path in wheels, tires, lowering springs and the KW DDC kit looks appealing long term. Also, good to see another ATL forum member here!

I've had a chance to install them. I was waiting for the car to set before posting the review. The first thing I noticed was the how soft the ride was in confort. I glides over most cracks and bumps on the road. There is still a bit of body roll in comfort. As soon as you put in sport that all changes. It stiffer and the body roll is gone. I prefer sport on the highway and and comfort on the local roads. I'm planning on getting VAC Monoball control arms to improve the steering feel. I will update this thread once I install and test them. Let me know if you want any details on the install or the ride. Last edited by badninja99; 06-20-2023 at 12:15 PM.. Reason: Typos |
