    Suspension geometry Q: E34 stuff

    There is a new product being released.

    I want to understand better exactly what this will do for my E34, and there is a hell of a lot better knowledge here than BF.c.

    I am not at all happy with my suspension setup. I want a more modern feel, I want more "planted" feel. I also hate the fuck out of my goddamn Bilstein Sports.

    Yup. Sports, in good shape, for sale, fucking soon. Just kidding, I will put them on a car I am selling.

    I have a plan on dampers and springs. I am hoping to do BC coilovers, but if not Justin wants to home-brew some coilovers for it. Either way it will have camber plates and some adjustable short body strut all around.

    I am not thinking anything too radical, like stitching in an E46 front clip, just some bolt on help. I plan on running a 225/40/18 on (hopefullly) an 18X8" wheel. I want a vertical sidewall on an 18" wheel, but I want narrow, for fuel economy. They will be pushed out to the edge of the body, but I want to have near stock camber at my normal "Static" height.

    All I do with this car is long drives. 400 mile road trips are common, but I work at home...no commute. I want it to be fairly low, but near stock camber.

    What I would like your brilliant and useful input on is this new product, as quoted from their thread on BF.c:

    Introducing a new suspension product for our e34's, the camber spacer.




    These spacers are a worthwhile addition to any e34 lowered by 1" or more. They bolt in between the strut and steering plate on each front strut assembly to achieve:

    Increased static negative camber (about 1.5 degree increase), keeps the outside upright when cornering for increased grip and reduced understeer.
    Raised front roll center, decreases body roll and improves steering response.
    Wider front track width, decreases weight transfer for increased cornering grip and reduced understeer.
    Restoration of factory anti-dive geometry, reduces dive under braking.
    Un-altered king pin inclination, conventional strut top camber plates increase KPI meaning that as the wheel is turned in a corner the increase in static negative camber is lost, not a problem with these camber spacers.
    No spring to strut tower clearance issues, normally you have to have coil-overs to get any more than an extra 0.5 degree of camber but these clear with ease.

    Of course there has to be a negative to balance against these positives and that is that these spacers increase the scrub radius, similar to running low offset wheel or wheel spacers. However I have had these plates installed on my car for some time now and have not experienced any adverse effects from the increase in scrub radius.

    The spacers are 1" thick and will clear most wheels 16" and larger.
    They are made from CNC Machined 6061 T6 High strength billet alloy, anodized black for an oem look. They are supplied will all the required high grade fasteners for installation.

    These spacers are available in limited quantity for $195.00 + Postage per set, with further stock being produced once sufficient demand has been established. Custom colors and sizes available upon request POA.

    Reply in this thread or send me a PM if you are interested in a set.

    Regards,
    Brendan

    They just look like roll center spacers, similar product exists for e30m3.

      Right...so how does that affect caster or camber, and how does that change the driving experience? Thats the shit I wanna know about...will this help get rid of some "push"?

        To the best of my understanding, it will take away some of the camber gain you get when lowering the car by adjusting the lower arm down closer to its original position.
        Mostly thou, they tend to help with bump steer.
        He best way to get neutral handling, or less push is:

        Make sure rear toe is in spec after lowering. This usually means kmac Rtabs or adjustable rear subframes (weld on). The camber curve is aggressive on e34s.
        The toe curve is even more so. I've seen cars lowered 50-60mm shift from toe in, to upto a degree of toe out. Very stable, but Eats the inner edge of the tire, not conducive to neutral handling.

        "Square" wheel set up. Wider rears=more traction at the rear=understeer

        Larger rear bar... Think the cheap oem upgrade is an M5 rear bar.
        Really big upgrade is m5t rear bar.

        Adjust tire pressures.

        I used to set my fronts to optimum pressure, by reading the tread pattern with water or blue snap line chalk, then run 3-4 psi more in the rear.
        Exact opposite of what the rules say to do, but effectively reduces rear contact patch and sidewall give for slightly LESS rear traction.

            AKG seemingly offers the same product in 2 different sizes

              Pretty much sums it up. Let me know on the progress of the 'home brew' coilovers. I'm thinking along the same lines...

                  They're way too stiff on e34s.

                    The local suspension dealer told me that if i wanted to run any spring a drop as large as -50mm the shocks needed to be Bilsteins.
                    Are there other shock options for running -50mm springs?

                      I dont know what youre talking about - my bilstein sports and H&R sports are cool. I still have the external bump stop on up front (I need to remove it) - I hit it sometimes but they ride decent. my front suspension is fairly worn out though

                          You havent seen pics of my new setup.

                          between my lip and the road I have an iphone of clearance. It is a functional setup - it will hold me over until Ground Controls

                              back needs the pads removed. Just need to rent a spring compressor
