    400/500 sway bar upgrade options?

    Hello,

    I have 1992 400E and looking for bigger sway bars.
    What are my options?
    I allready bought R129 500 30mm front bar so i would need something to compensate that on back, or full set.

    1. E500E 28mm&18mm bars? Cant find used here in my country, maybe new ones from the dealer or here?

    2. Those reproduction bars, any news on those topics?

    3. W210 Amg/H&r 20mm rear bar, i read somewhere here that it wouldnt fit W124 V8 engined cars due to different subframe?

    4. Read somewhere that somebody put R171 rear bar, but dont know was his car V8 engined or not?

    5. Local guy who can make me new bar(s) within 30mm-14mm for few hundred, but he's out of work for atleast two months(injured, dont really know when he returns)

    Put some facts on the table!

    Also you can offer me if you have something for sale, but the price range must be in hundreds not thousands for my budjet.

    Have you installed the R129 front bar? I'm not sure if it will fit at all, and may at least require modifying the mounting brackets. The shape is different.

    If the R129 front bar works, just buy a new 500E rear bar. There's nothing else available without having a full custom set produced, and unless your local guy has made custom Mercedes bars before with multiple bends, I'm not confident he'll be able to make them that cheap.

    Gsxr, i havent installed the R129 500 bar yet. Waiting to get it and yes i have read about that inner mounting modification needed.

    If i cant get any other rear bar then ill buy that 500e bar.

    This guy/company is very experienced on springs and swaybars, they have done those over 35 years and they do those essentially for rallycars and said to me that could make a 30mm/20mm kit for 500€

    On the Facebook there is also this company Hedgehog motorsport, have you heard? They have nice w201 projects and make custom parts for them. Also some for w124/r129. They have for sale w201 rear bars 19mm for 130usd and 22mm for 140usd if i remember correct.
    I asked them and they could make w124 32/22 bar kit for 400usd but the shipping would be something like 200-300usd to me + 25% tax.

    So just weighting my options now.

    I had Bilstein B8 struts and bilstein lowering springs but now i sold them because i bought YellowSpeed Racing adjustable strut and spring kit. Really want to get thicker sways because dont want to scratch my sidemirrors on the ground anymore when cornering

    It’s too bad that the Feind Motorsports rear bars are NLA. I have a new one in my long-term parts stash.

    The 129 bar fits but it is to far forward. So the mounts are flexed. It works but it is not right. Really just some billet mounts on swivels would be best.
    The rear bar I have used w210 ones and now have the r171 rear bar in. It was like 55.00 when I bought it. It is a little to bit long but some custom bent and reinforced links and or bending the end of the sway bar in an 1" on each side. I am widening my rear track on my car so not needed.
    And of course the 500e bars are direct fit as said.

    Hey, whipplem104
    But was your car 034 or 036? Because i heard that w210 wouldnt fit to rear V8 engined due to different subframe than on smaller engine 124`s.

    I just finished making mounts for r129 bar and now im having a chat with one guy overseas if he could make me rear bar, i mean he can make one but what would the price be.

    No but I think I had the v8 subframe in the car at the time. I think what you are talking about is that they rub on the front tubular section. I put a piece of felt on there if I remember. I think it was a possible contact point but it rubbed the paint off on the felt and that was it. The only interference point I had was that part would rub on my fuel feed line. It was barely touching. The ones that have an elbow on them did not touch.
    Honestly just get the 500e one. They are not that expensive. If you want something bigger then you really ought to be looking at other suspension parts like shocks and springs and weight. And money for the sway bar will start to look cheap. I am really considering building a push rod/bell crank setup for mine some day. Only way to put proper shocks and springs in the rear end.

    500e rears are NLA.
    210 e55 rear are plentiful.
    Cool idea on the bell cranks. Bust out the solidworks and the cnc plasma.

    I'm almost positive the W210 E55 rear bar will not fit the .034/.036, as the fuel tank outlet hose interferes... the E55 bar shape is wrong.

    I think the E55 bar fits 124's without V8 engines if the fuel outlet (which is smaller) is bent slightly for clearance. (??)

    I had upgraded to w210 AMG rear bar on my 1987 w124 AMG project car Dave.

    IIRC I made custom mounts and shifted them forward by a few mm so it cleared properly. I'll dig out pics and post them later

    So this was the old 200 bar VS the w210 AMG Bar:

    IMG_0027.JPG

    Custom brackets made from decent thickness mild steel. Look approx like OE also using the w210 cast brackets:

    IMG_0110.JPG

    The w210 sway bar did foul the fuel line when first offered up. I did slide the new mount location forward on the car and welded them on so as to create a clear 4mm or so clearance to the fuel line. Went back together nice:

    Note: This 3.6 AMG swap project car is still unfinished and has not been driven so I cannot comment on specific handling improvements or characteristics as yet.

    Hi.

    I have the w210 E55 H&R rear swaybar on my 500E-91.
    Tight with fuel tank outlet hose but no problems!
    Did the first test this week with H&R E55 springs to......
    Nice handling!

    Anders.
