    M3 links can bind while lifting the front. http://www.r3vlimited.com/board/showthread.php?t=201219

    So you can either mount the tab up high on the strut and have the bar not be horizontal, down low and have the bar horizontal (with binding at max travel/tire lift situation), or go the route of adjustable/custom links with the tab mounted high, ideal but a few extra dollars. For pretty much the same price you can just get a chunky front bar like IEs 25mm hollow, and as long as you aren't slammed it shouldn't bind. From what I gather HR races don't cause binding, and are about as low as a person can get without coil overs.

    more stuff that swayed my opinion on m3 links http://www.r3vlimited.com/board/show...=269462&page=3

    I just don't see why people go through the effort when for almost the same amount of money you don't have to weld in tabs and figure out the right length links just to not bind in a different way. For the m3 links to be a necessity one would have to be low enough to where stock links bind, but going hella low fucks suspension geometry and thus the handling on e30s. Me thinks people concerned about sway bars care about handling and aren't super low.

    Not trying to argue, just a different perspective. Apparently a little lift isn't that bad, but if I'm going to lift the inside front tire leaving the apex under heavy throttle I'm not going to be binding while I do it, and I will take the easy route of doing so.
    Thanks for the links! those give some more things to watch out for when swapping my car to the e30m3 front struts.

    e36's are the same in that the non M cars have control arm mounted end links and the M's have shock mounted end links.

    My understanding was the reason the Strut mounted links were preferred from a performance stand point is you get a more linear 1:1 ratio with suspension travel to sway bar torque vs mounting further in on the control arm?

    Flat bit of rocker- so pretty low.

    It also depends a lot on the make of stock- type bar- they're all somewhat different in shape,
    and provided linkage.

    We can't use the M3 points, legally.

    I had luck reducing bind by making shorter links out of heim ends, but it's not optimal.

    is that 5" to the bottom of the seam or the actual rocker?

    i really need to get an upgraded front bar and some adjustable links--i have GCs with tabs welded to the strut but still using stock bar and stock links attached to the control arms

    ...I later thought to myself that this is not as much of a faux pas as Porsche shipping 911s with open diffs.

    Maybe has something to do with the X5's higher CoG? The ute needs more help from the sways?

    my comment was about non-m3s.

    If you're lifting the inside front, you probably need more rear spring.

If insane stiffness is what you are after IE makes a hollow 25mm, addco makes a solid one incher.From what I've gathered both are overkill, and it seems that stanced cars are the ones binding at the links.

    I crunched numbers and the ie hollow should be ~166% the stiffness of the 22mm most people use, the addco bar ~177% stiffness of the 22mm. This is if the materials used are apples to apples in terms of metal used.
