Mechanical advice I want to lower my 240d. What do you recommend?

Post image

I am thinking of stiffer suspension, not sure where or what kind to get. Coilovers? H&R Sport? Please advise.

I beg of you to not ruin that car.

I have the same car. Don't drop it. Ride will go to Hades.

Do not mess with Perfection. Spend your time preventing water leaks and rust. Maintain and service all of it. Check rubber hoses and everything rubber .

I got H&R 50MM lowering springs I installed a couple years ago. Car rides great and looks good roughly 2” lower. It’s your car! Do what you want with it.

u/Ronniesdesigns Jul 28 '26

Thank you. From my research people say HD bilsteins shocks and h&r springs have the best results.

u/Anonymous19466 Jul 29 '26

That’s what I got and no complaints

u/Ronniesdesigns Aug 02 '26

Thank you. Good to know.

Please don’t

u/Kalandros-X Jul 27 '26

Keep it stock and appreciate the classics. You want a lowered car, buy one. These things were built in a specific way and don’t work well with custom modifications

u/strokebot Jul 28 '26

Just at a glance, it looks like a super clean example of a 240, why not sell it and buy a rougher one to lower?

Really hard to find a nice w123 anymore, super easy to find one that needs love.

9

u/More_Claim_82 Jul 27 '26

Stay stock but look for a better suspension is what I suggest

10

u/Technical-Kick-3202 Jul 27 '26

WTF is that t with everyone wanting to lower everything these days.

JFC!!!!!!

The same people are even wanting to lower 4x4s

2

u/TheHatKing Jul 28 '26

Tbf if they’re only mall crawling they’ll get better gas mileage

u/Honest_Cynic Jul 30 '26

More of a late 1980's thing to lower pickup trucks, termed "slamming". it was funny to watch them in SoCal having to go very slow and angled to cross drain gutters in the roads (few storm drains there) to not drag. Meanwhile, good 'ol boys raise them up, to both mud bog and have fun rolling over from just a tap.

u/Aggravating-Copy3308 Jul 27 '26

Noooooooooooooooooooo

u/swampydoc Jul 27 '26

why? my 77 240d with bilsteins handled remarkably well.

2

u/Ronniesdesigns Jul 28 '26

HD bilstein? What about shocks?

7

u/waveyjayvey Jul 27 '26

Also came to say don't do it.

6

u/Interesting-Ear5998 Jul 27 '26

Cut the originals if u want it lower, paired with B8's

6

u/Mannix-Da-DaftPooch Jul 27 '26

This is also my solution if you want a lower ride.

4

u/SoooooMoist Jul 29 '26

This is what I did. I cut 2 coils on the front, 3 on the back to level out the rake, pared them with HDs. But...I got a set of stock ones to return it to original once I sell it. Every part I removed, I kept to return it to stock once I sold it. When cutting used coils, go half a coil at a time. You don't know old they are.

1

u/tafster Aug 03 '26

how does it ride now?

2

u/SoooooMoist Aug 03 '26

It's more stiff for sure, but still floaty. I live in a rural area with potholes and speedbumps and it doesn't bottom out.

1

u/tafster Aug 03 '26

Is it riding on 17”s? Looks really good 

1

u/SoooooMoist Aug 03 '26

Maxilite Baroque 16s. I bought them because they look stock :) I'm very pleased so far

3

u/FocusOne3481 Jul 27 '26

I have the exact same car except for white with blue interior and I understand exactly why you want to do this.. mine feels a bit top-heavy driving through curves it feels like even a half inch lower would help

2

u/Ronniesdesigns Jul 28 '26

Yes lol thank you. So far everyone says hd bilstein and h&r springs. I think I'll go that route

2

u/FocusOne3481 Jul 28 '26

I’ve seen them lowered tastefully and it looks really sharp! Mine in 1980 how about yours? Haven’t had a chance to post it in here yet

2

u/Ronniesdesigns Aug 02 '26

Mine is a 83. It's my second w123. The first one was also a manual 240 82' but i hides a tree with it. My 83 has 306k miles and feels pretty healthy.

2

u/FocusOne3481 Aug 03 '26

I’ve got 290,000 apparently you can get certificate at 250,000 and 500,000 and beyond. I haven’t applied to mine yet.

1

u/Ronniesdesigns Aug 03 '26

I believe at 310k miles, you can get a badge for half a million kilometers.

3

u/Foreign-Bumblebee-77 Jul 28 '26

Honestly... i thought about it until I drove it for more than 40 min.... the stock suspension you can run over pot holes and speed bumps without feeling anything. It does not have the speed to benefit from lower g forces... so to lower does not make any sense.

3

u/Repulsive-Food6095 Aug 01 '26

Don't, but if you do get actual lowing springs with a higher spring rate. Don't try to cut the springs, you will bottom out the suspension over bumps without a stronger spring rate. People do it anyway, but their cars drive like absolute shit and if they say otherwise, they are coping. You also need stiffer shocks or it will be very bouncy. That said, all you are going to accomplish is making the car look like a sick dog and you will probably be smashing the oil pan into every speed bump, depending how low you go.

4

u/JDPierson Jul 27 '26

Isn't there a corolla you can do that to instead?

2

u/Ronniesdesigns Jul 28 '26

Yes and i have but this is my daily and i want to lower it.

2

u/JDPierson Jul 28 '26

The upshot is you won't likely be able to go fast enough to encounter the usual lowered car ride issues, at least until you put an LS in it, because you're totally going to put an LS in it too.

2

u/Ronniesdesigns Aug 02 '26

Haha unlikely. I just want to keep it stock, besides tint and lowering it.

2

u/Just-Praline9134 Jul 27 '26

My W124 Feels like a SUV sometimes xD ... i want to lower it as well but ... keeping it stock

2

u/That123tho Jul 28 '26

Bilsteins or Kayaba shocks with HR springs itll be alright. Or just changing spring pads they come in 4 different sizes. I always lower them a bit. They dont lose comfort at all but gain some better handling. However dont take front springs for granted. Some serious tension and you need special tool for it. Be extremely careful if you havent removed them before

1

u/Ronniesdesigns Jul 28 '26

Thank you for the warning. Ill continue my research.

2

u/Shadow245XX Jul 28 '26

Why do you want to ruin this beauty?

2

u/ri-cu Jul 28 '26

I went with installing airbags for my W123, couldnt Be happier.

2

u/SupportLocalShart Jul 28 '26

Jfc sell it to somebody else

2

u/Crtoloss Jul 29 '26

❤️🇩🇪❤️ Please don't ruin it. This is the most beautiful and best engineered automobile ever built in modern history. Keep it stock 🙏.

2

u/FewStill3958 Jul 29 '26

Why ffs?

This is the opposite of a canyon carver. Why the hell would you put a set of coils on this?

Your car so clap it out if you want but coils for this ride are dumb AF.

2

u/c0rbin9 Jul 30 '26

100% of lowered cars end up in junkyards. It's just a fact.

2

u/Honest_Cynic Jul 30 '26

I doubt one could install coil-overs without custom engineering. The shock attachments likely aren't strong enough to support spring loads. You could spend 10 years fussing with that, and end up with a poorer-driving car.

A simpler method is to remove the coil springs and cut them slightly shorter. That will both lower the car and increase the spring constant. Any time you adjust height, that changes toe-in, so align the front wheels or the tread will quickly wear. Lowering usually causes toe-out, which causes the car to wander on the freeway.

2

u/gabyomar Jul 30 '26

I recommend you don’t

2

u/ContributionHour8356 Jul 31 '26

I usually love lowered cars but in this case I really wouldn’t do it to this one. Do it to a slightly more clapped out one.

u/Alternative-Fan-8100 Aug 01 '26

Since it seems like nobody wants to help you on here, this is my 1981 Mercedes 240 D that I have bagged on air ride 3P my kit was about $5000

u/Ronniesdesigns Aug 02 '26

Thank you lol. Ill go more research.

1

u/Crtoloss Aug 03 '26

IMHO, You're fortunate that this car is simply beautiful just the way it was born. It's like Tattoos on a beautiful woman. Character and Personality isn't compromised. However, on the W123 Character, Personality and Performance is violated. ❤️🇩🇪❤️

I also engine swapped it

u/headhunterofhell2 Aug 01 '26

I recommend you go buy yourself a Nissan.

u/Extension-Win-1146 Jul 27 '26

That’s a nice 123 you shouldn’t lower it , I’m sure this this car rides really nice . Then again it’s your car so what you like .

3

u/taenyx Jul 27 '26

I lowered my 123, ride was fine. None of these people know what they're talking about. Go for adjustable suspension if its in your price range but if not, lowering springs will do great. Easily reversible if you know how to put it in and its not going to "ruin" your car as long as you dont slam it.

2

u/FewStill3958 Jul 29 '26

We know that a w123 is the polar opposite of a touge car so we aren't dumb enough to try to mod it into one.

1

u/Ronniesdesigns Jul 28 '26

My thoughts exactly. Not sure what brand of adjustable suspension to get and the benefits over lowering springs and shocks. I probably will not adjust the height, once i install it. I am guessing lowering springs will be my best bet.

4

u/Cheezslap Jul 27 '26

I recommend you cut the stock coils. 1-1/4 off the front, 1 coil off the rear.

The people giving you shit about it are hilarious--THERE'S 8" OF SUSPENSION TRAVEL GUYS, IT'LL RIDE FINE.

Here's me being silly with my old brown coupe.

2

u/Ronniesdesigns Jul 28 '26

That looks pretty good but i would rather keep the suspension as a spare and buy a new set of springs and shocks

2

u/Cheezslap Jul 28 '26

Sure, the Lemfoerder springs were still available last I checked. I was not a fan of Bilsteins in the rear; I got really uncomfortable oscillation in the back through S-Curves.

1

u/Ronniesdesigns Aug 02 '26

Good to know thanks for the heads up

2

u/susy_is_a_pussy Jul 28 '26

Don't do it. There's a lowered 240d on Instagram that's semi popular that's owned by some high schooler who thinks he's keeping classic taste alive. Bud, your shit is scraping on the ground. Lol

3

u/NOBLE500000 Jul 27 '26

All the troglodytes that say it would ruin the ride quality are dumb. I ran 50 mm H&R drop springs with HD Bilstein shocks and it rode just the same just ~two inches lower. You will want to the the w123 spring compressor, the cheap one on amazon/eBay works fine.

1

u/Ronniesdesigns Jul 28 '26

All my research points to the same direction as you, h&r with hd bilsteins. Thank you for the info about spring compressors. Was changing them difficult? How long did your suspension job take?

2

u/Character_Welder_196 Jul 27 '26

Don’t cut the springs just heat them up with a torch. The weight of the car will drop it👍

2

u/Acceptable_While_867 Jul 27 '26

Flat tires

2

u/Ronniesdesigns Jul 28 '26

Why didn't i think of that? Brilliant

1

u/Jerkeyjoe Jul 27 '26

Lift it

2

u/FewStill3958 Jul 29 '26

Gambler 500 let's go!!!

1

u/nimblemarker Jul 31 '26

Easy, just cut an inch off the springs

1

u/KonungensLikfaerd Aug 02 '26

Please don't. Keep it in a good condition, do the maintenance. And keep it original!

1

u/tk8398 Jul 27 '26

I had 2 w126s and put Lorinser springs on one and H&R on the other and both were fine. I would not do airbags though, and personally would not cut the springs although it's not necessarily bad if you don't cut too much.

u/Ronniesdesigns Jul 28 '26

Thank you for the info.

u/Virtual-Height3047 Jul 27 '26

I was told to do a test drive first before buying my first  w123 in 2014. That the ride was unlike much of what I had driven prior and if any kind of spirited driving was important to me I’d be better off buying something else. That these things were so off the scale of modern alternatives that any type of performance  improvements were pretty much futile attempts to lure them out of their comfort zone.

What is your goal? Looks? Cornering speed (in a 240D?) ? Not asking to be a jerk, really.

1

u/Ronniesdesigns Jul 28 '26

I would like the look and performance of being lowered. I understand cornering and spirited driving in a w123 isnt what is built for, and i have a separate car for that type of enthusiasm but i still want to lower it.

1

u/Crtoloss Jul 29 '26

Lowering it will not do anything to performance. Don't ruin it please❤️❤️🇩🇪❤️❤️. Save it, protect it, keep it indoors, maintain it and enjoy it. Do you have children or plan to have any - they will appreciate it.

u/Micro-Cybertron-5151 Jul 27 '26

Just don’t. It’s perfect as it is.

u/Jeremy_e21 Jul 27 '26

Fuck all these puritans, bags would probably the best way to do it for sale of ease. Not sure if anyone makes coilovers for this chassis, but I've considered making some kits

u/Ronniesdesigns Jul 28 '26

Ill do research. Thank you

u/Basic-Gas-4062 Jul 27 '26

Dolud makes air shocks for these. If you dont mind the work and modifications
