    Help me fix my setup, yay!

    My car has some wicked oversteer with the rear sway in place, and I'd like to find a solution better than my temporary "fix" of unhooking it. Part of it may or really is the reduced camber in the back thanks to the eccentric bushings I have.

    I'm going to try to get my rear suspension lower out of two ways: 1) somehow getting the bolt loosened or cutting it and lowering perch (but this wouldn't help the coil binding) 2) get old adjuster off and replace with a 2.5" ID one and run my 5.5" 475# spring instead of my 6" one...


    As far as balancing it better, there are several options

    a) Do what Jay suggests and get a 375# (or 400# even) front spring. Cost: $120 + pain of installing
    i) could also install m3 tabs and run the different pickup for the front bar for more body roll killage

    b) install m3 tabs. i have the parts already, but wouldn't be fun to install. but would make my bar act like a ~24mm one

    c) install ST bar or IE 25mm hollow bar (which would be ~23mm solid maybe, and lighter). run 325 endlinks still. (no preload on bar though)
    i) run a 25mm IE bar, with m3 links, and 400# front springs, with something like 550# 5.5" rear springs and stock rear sway ?

    d) buy IE stage 3 springs and install with my Konis.
    i) possibly buy a swaybar set after that


    my ultimate goal is making my car solid handling and not so creaky, and pretty comfortable for a daily. 400# springs might be stiffer and be less comfy than a swaybar fix in front. I plan on doing more auto-x and less track in the future, but don't care to be fast as real stiff springs would require


    throw your $.02 in the ring and help me out

    M3 Tabs and links get my vote. I'm running them on my 85 325e, with a 21mm front and 14.5 rear it's about perfect. I am running a longer link then the m3 one so that helps the front bar be more effective, and also I helped elminate this issue I had some extreme angles and preload going on, I may of had the m3 tab welded to high up(right below the spring perech). But I put in some custom made adjustable links, that are almost 2 inches longer then stock, to dial it out. I'm getting just a tad hint of understeer with the current setup.

      hmmm. i'd possibly go for the m3 setup.

      or IE 22mm front adjustable one for $215...

        I just don't see the justification of going for the I&E bar when you can make your stock bar behave just like the ireland bar.

            maybe if I customize the cabby bar with a couple adjustment holes



            # Custom Adjustable TRD

            The standard TRD bar can be modified to make an adjustable bar. Mine has three attachment holes at approx. 38%, 70%, and 112% stiffer than stock. Picture of the Custom Adjustable TRD bar Technical Article

              Looking at mine - I think you can get one extra hold per side on the cabby bar, not two.

                What class are you going to be running in?

                    I've thought my self about moding the stock bar, I figured I'd just have a plate welded one i could drill holes into.

                      I think I'd be more comfortable with the crush and drill approach.

                        With adjustable links you can get almost the same affect also.

                          Is the oversteer constant (through out every corner, going in or coming out?) Under full load on the rear or only in certain turns?

                          You still running Falkens right?

                              I only remember certain turns etched into my memory, and although it seemed like throughout the whole turn, if anything it was going into one.
