    Default CX "Wallowing" - How to stiffen up suspension?

    I have a CX 25 DTR Turbo, and I am not happy with it "wallowing" on the freeway at speed. If I go over a slight rise, it keeps "wallowing" a bit until it settles again. I suspect this is what many like and see as a soft ride. I would like a firmer ride and slightly more sporty feel.

    Would I be better going for GTi "turbo" spheres for this purpose? I see it mentioned elsewhere that they have smaller damping holes.

    And how much difference do the Series II anti-roll bars make to the handling and ride? Do they only influence the roll, or do they also influence the ride?
    I have a Series II parts car i can get the front and rear roll bars out of if they will make a difference. I also have a Series II TDR and it seems to handle better than my Series I. I often sit on 150-170 in the Series II in Europe, but I cannot do that in the Series I in Australia.

    Everything else on the suspension seems to be operating correctly.

    What can any of you advise?

    Hi, don't understand " wallowing ", do you mean wandering? Over inflated spheres will increase softer ride, check your sphere pressures .
    Rear suspension arm pivot bearings, when worn cause unstable swaying on undulating surfaces.
    Check with unloaded suspension for side play, there should be none.
    Hope this helps.
    Cheers

    Anti-roll bars have no effect on ride if left & right wheels both hit the bump (say, a tranverse ridge in the road). It simply swivels.

    If only one wheel hits the bump (say, a pothole) then the bar acts as an extra springing medium as it is torsionally twisted.

    Sorry Birks, what I mean is that it bounces a couple of times before settling in again. Basically it is just too soft for my liking. The Series II is better, and I thought this was because of different damping, but now I see they all have the same spheres.

    The rear suspension arm bearings are fine, there is no binding and they are smooth and effortless. Sphere pressures should be reasonable I feel, but I will get them all checked before long. But they are certainly not over inflated.

    I am simply wondering if GTi spheres will give me this firmer ride with less bouncing at speed? Thanks for the confirmation on how the anti-roll bars work 4cvg, I suspected such was the case.

    Pull the spheres off and check them. See if someone ( like me ) has accidently fitted the wrong sphere ... eg: GS sphere/accumulator ( ) on the back of the car.

    A couple of videos from over 10 years ago

    BX with wrong rear spheres

    https://youtu.be/zcgQKMfzmlU

    Correct spheres

    https://www.youtube.com/watch?v=f4H7ux0BzKQ

    Maybe there is something in this for you?

    Thanks Shane, I never thought of that. I fitted the correct spheres to the front a couple of years ago, but the rears seemed okay at the time (that is they were soft with good travel), so I will do this. I certainly need to check the accumulator sphere anyway, so will check them all.

    Thanks for the videos UFO, and it prompted me to video mine for you. I tried to attach it but was not able to. apparently it needs to be a YouTube video for me to do that? If someone can tell me how to attach my own video I will?

    It appears quite normal to me. The back bounces a bit more than the front though. What I think is that if the back end is a little firmer it will settle the whole car down.

    Mine is pretty soft but it doesn't rebound twice. My suspicion would be wrong spheres too. Might only be one of them? Just about to put new rears on myself!

    Typically mismatched front / rear spheres will make one or the other end of the car " wallow " or float. Failing rear spheres will cause the front to float as will failing front ones cause the rear to float sickenly. Mismatched damping will do much the same. Those who experiment mostly revert back to factory sets.

    Thanks for all your help gentlemen. I will check for the correct spheres and pressures in the next week or so, and report back.

    Talking about "wallowing", I followed this bmw a few days ago on the Sunshine Motorway, perfectly good surface, then the car starts wallowing in front of me. What the ?

    A few years ago we had a large Benz living locally that was completely rigid in the suspension and pointed to the sky as well. No doubt dead spheres and I suspect the owner didn't know any better.
    It is an interesting exercise to watch cars as people enter and leave their vehicles. Most BMWs do not move, ie no compression of springs when loaded...the ultimate driving machine experience.
