    GC suspension set up / sway bar questions

    I currently am in the process of swaping my suspension out of my daily into another car (new daily) and am looking to upgrade the sways.
    Currently i have:
    -New control arms
    -New sway links
    -G.C caster camber plates
    -M3 offset CAB's
    -Koni adjustables all the way around (full stiff rear, 4-5 stiff front)
    -Ebiach 450f-6" 700r-6"
    -I.E. poly street subframe and control arm bushings
    -All new bremo blanks, hawk hps', rebuilt calipers and stainless brake lines
    -I believe what are e46 cabrio rear shock mounts...came with the car
    -Stock i sway bars

    I will hopefully be running The new 225/45-15 hancook rs-3 as i figure the tire wear can't be that much worse than my current bottle cap and azenis set up. I think the wider tires should dramatically help in grip with this set up.

    This is all stuff ive collected over time and put in my old daily. THe budget is tight for sways...very tight

    I am currently looking for an ix rear bar and a cabrio front.

    I feel this would pretty much keep the feel of my current set up but with less roll (not that the car has alot of roll currently). I thought about running m3 sway links in the front but i think that for the rear bar it would be to much front stifness, though im shure i could soften up the front struts some to help balance this out. Would running these bars with new bushings and stock front mounting location be a noticable differance over stock bars?

    Any comments will be much appreciated as allways!

    You should probably set up any rear sway bar with the mounts that bolt into the trunk.
    Like the IE setup. I run the 25mm/22mm setup from those guys. Tight and right.

      Hook up the front sway bar like an M3.

      Here is a good way to think about it:

      You have made several changes to increase the grip of your front tires. They can do more WORK now. Go ahead and tell the tires to do more work, with a stiffer front bar (m3 hookup makes the tire think the sway bar is stiffer.)

      When you make it so the tires are capable of doing more work, and then you lean on them to do more work, then the amount of work (as in grip) is greater. Therefore the car is faster.

      You can tune the car with various stock sway bars. If the Vert bar is too much, throw on a 325is bar, but still in the M3 position.

      I suspect you will end up with 2.5 neg camber front, Vert front bar in M3 position, and m3 rear bar (or even 325is if you dont have an m3 rear bar)

        How much do those tabs run for the m3 sway bar linkage? Is there an absolute position where they should be mounted.

        I was originally going to run stock front bar no rear sway which is the reason for running higher spring rates in the rear. So i think the stiffer m3 linked cabrio with the softer ix in the rear it should actually balance it out pretty well.

            Apparently the bushings were super old and pretty much disinagrated. So i had to try and find new poly replacements. The 16mm proved to be a descent challenge.
