My 2017 340i came with passive dampeners/springs, and it always felt floaty and crashy against potholes. And sat way too high. I swapped them for Eiback sport lowering springs, and Bilstein B8 dampeners (in-built bump stops) and its completely transformed the ride. Still comfortable but way more assured with cornering and dealing with potholes. And it looks amazing lowered compared to factory setup. Very happy now.
Kern has a video to answer any decision I’ve made with my RWD 340i so far. Appreciate you so much my dude. Just bought some pretty aggressive wheels from Apex (19x9 et28 F and 19x9.5 et33) and I wanted an aesthetic drop to complete the look without ruining the ride too much more (Adaptive M dampers)… Prior to this video H&R Sport seemed like the answer leaving a finger or two gap and barely changing the ride+adding another -0.5 of caber to help keep the wheels from rubbing in the back (275 rear tire for traction). Of course there is a Kern video where he literally has a RWD 340i with adaptive suspension and H&R Sports. Your coverage of the topics is so helpful to the community. Your videos have helped solidify my choices on multiple mods. Stage 2+ (TU pump and DP on MHD and Sutphin trans tune) plus some wheels and H&R springs makes for a perfect daily driver for aggressive street application. Thank you Kern!
I installed KW V2 coilovers paired with my 17inch Apex Wheels, 245/45/17 square setup! The car handles corners amazing! My next step forsure is the sway bars, and camber plates for the front as well! Edit: My 2018 BMW 340i xDrive did come equipped with EDC suspension, luckily KW has an option for the EDC Delete!
Please keep in mind that lowering springs - especially these H&R spring which are pretty low - often damage the (rear) damper or bump stump quickly Great you added these info in your video at 8:30
I've installed on my 440ix f36 KW DDC. Which works with the adaptive computer, no need to code and they ride 10 times better, much less roll as well, more much stiff, yet much more comfortable in any scenarios. Made me faster on track, and made me have way more confident in the car on shitty roads
@@tamcra5357 the DDC isn't any of the above, it's a different model. You have the ones you mentioned, and also the DDC. I can only guess they are like the v3, but electrically controlled. Done it changes compression and rebound on the fly.
I like my 340xi msport with adaptive and hr sport springs. Still rides very nice in eco/comfort, but in sport/sport+ it handles. Been a nice compromise between coilovers, and stock suspension. Only thing that concerns me is having to replace the adaptive suspension at some point lol. It's gonna hurt the wallet.
What’s up Kern!!! This is my first video of yours I’ve ever seen and it definitely won’t be my last. I have a 2021 m340 xdrive that I daily as a traveling salesmen I probably do 20k miles a year. Do you think v2 kw coils would be a good move for me. I’m trying to have the least amount of issues as possible and spend the money on the front end so I don’t have expensive repairs come up. I’m just looking for a little bit of improved looks and performance that’s all. Not racing or anything crazy just normal daily driving and racing around with my buddys from time to time. Any thoughts would be awesome thanks bro!!
hey i have a 2024 330i m package, I wanna lower it a little with some coilovers but I'm concerned about removing the stock adaptive suspension. Will removing the stock suspension throw a error code in the system?
I put H&R sports springs on my F80 and it was the worst thing I did! It looked perfect but the ride was awful it was crashy and the steering just felt weird too! I only managed it for a few weeks before swapping it out for new Bilstein shocks and that made it perfect.
Any feedback on the front and rear sway bars upgrade along with your lowering springs? Did the sway bar have any negative effect on handling over bumps?
@@kern417 factory alignment specs. I have lowering springs from old owner, not sure the brand. And for some reason, tires are feathering and making noise because camber is out in front and they can’t get aligned.
Camber shouldn't cause excessive wear on your tires. Make sure that your toe is inspect and if camber is two different from left to rear, there may be a bent control arm or something else causing issues.
I unfortunately dont have the adaptive suspension - only static. Is it worth I sell my 340i and replace it with another 340i with adaptive suspension? Is it really that big of a difference?
What are your thoughts on lowering spring on xdrive I heard it messes up the transfer case and coilovers are better is this true? I have a 2019 440i grand coupe xdrive and I’m wondering what’s the best route for lowering my car if possible could you please do a video for us xdrive guys because I heard certain setups messes up our xdrive system.
Lowering springs work fine on xdrive. If anything coilovers can be more dangerous if you lower the car too much. It's not about the suspension so much as the ride height you go with because you can't lower xDrive cars too far or else it will damage axles.
I currently own a 440 x drive and was thinking of getting the sport springs. I have 66k miles, do you think my shocks will wear out fast or would everything be fine.
I recommend doing Sway Bars first. Here's why: ruclips.net/video/HPE0pXHu-MA/видео.html

Can you comment on having a front strut bar installed? For Macpherson struts it should on paper be a good upgrade
what are your thoughts on the dinan springs and bump stop combo with the thicker sway bars?
Will removing adaptive suspension affect sport+ mode in regards to throttle response?
hey i have a 2024 330i m package, I wanna lower it a little with some coilovers but I'm concerned about removing the stock adaptive suspension. Will removing the stock suspension throw a error code in the system?

Sorry to hear. Mine are great 🤩
@@kern417 yeah I’m wondering if something else was wrong that would cause it
You ever try the mss adjustable springs?
Are there any info available about the spring rates of these aftermarket springs ?
Any feedback on the front and rear sway bars upgrade along with your lowering springs? Did the sway bar have any negative effect on handling over bumps?
not noticeable
Stiff rear anti roll bar will have negative impact to traction.
I‘d fit an LSD at the same time as the ARB
What was the front and rear sway bars diameters you used?
H&R. They have the biggest diameter solid sway bars on the market. The car still drives great and comfortable.
I'm looking into dinan springs with their bump stops. Would you not get their bump stops since you said bump stops is what ruins the ride?
Correct i would not. Their bump stops are just up-priced oem ones anyway
Which setup provides the best stock alignment specs so tires don’t wear as quickly on daily drivers?
which alignment specs? with springs it's not really an issue.
@@kern417 factory alignment specs. I have lowering springs from old owner, not sure the brand. And for some reason, tires are feathering and making noise because camber is out in front and they can’t get aligned.
Camber shouldn't cause excessive wear on your tires. Make sure that your toe is inspect and if camber is two different from left to rear, there may be a bent control arm or something else causing issues.
I unfortunately dont have the adaptive suspension - only static. Is it worth I sell my 340i and replace it with another 340i with adaptive suspension? Is it really that big of a difference?
not worth it unless you get an incredible deal. but i definitely think it's worth it if you're looking for one

@@kern417 so that means the h&r sport springs should be ok with no harm to my axles?
@@ajaniwatson9220 correct. Sport springs do not lower it so much to damage any xdrive components.
If you were to go with a coilover setup what brand coilovers would you go with I plan on going kw v2s for my 340i xdrive
i have kw v1 on my 440i
would you say its similar results on f22 m240? think i should still do sway bar first even tho smaller wheelbase?
yes
yes and yes
M140 / M240 already has stiffer rear ARB as 340i
@@vollcare4076m240i has a stiffer rear rear bar only. The front bar is the same as in 340i and 440i
I installed Dinan bump stops with Dinan shocks should i put the other stock stops back on I’ve had no bottoming out issues at all
i would
My M240 xdrive has the Adaptive and im a fan
Still thinking maybe springs and slight drop might be needed, maybe sways
Sway bars make a hell of a difference
Sway bars first if performance and handling is a priority
hi kern was wondering if lowering xdrive car will break axels what are your thoughts
If you lower it too much you can. Just don't make it too aggressive.
@@kern417 i don’t have wheel gap is that too much? what do you mean by aggressive thanks kern! money is tight so i don’t want to break an axel
I currently own a 440 x drive and was thinking of getting the sport springs. I have 66k miles, do you think my shocks will wear out fast or would everything be fine.
should be fine
@@kern417ok thanks appreciate it
Lowing spring is mostly for looks only
Great for performance
is it possible to mod in the adaptive?
The only company i know that sells a custom "tune" for adaptive suspension os Dinan. But I haven't tried it and don't really see a need to.
@@kern417 oh I mean I have base suspension and want to upgrade, not tune the adaptive, unless that's what you are saying dinan has
oh no, you have to have the shocks and wiring and custom coding to make it work. not really worth it.
@@kern417 yeah just go coilovers at that point
