    the pieces need to be 1.75" by 14.5" you could extend them to 16.5" but you will need to bend them to fit the curves of the arms.

    People are dumbasses. I dunno much about suspension crap, but is this really gonna help? Hows this work? Is it good for the twisties, or drag racing? Also, what exactly are you converting later?

    it will maintain the suspension geometry, which makes the handeling more predictable.
    i am going to convert to coil-overs, tubular control arms with rod ends, possibly a torque arm, and a watts-link

    It'll help all around. Any deflection, whether in the frame or suspension components, consumes reaction time, so it can't hurt acceleartion off the line. And like Duceandahalf said it helps maintain consistency in the corners. The Mustang guys get hung up on bind because Mustangs will bind with hard urethane or solid aluminum bushings, mostly because the control arms really made too short cuz of space issues. Besides that, the lower also has to bear the stress of the spring on a Mustang. That's why the 05 stang has a 3-link w/panhard bar.

    This is a great mod. General Motors did it as a 'factory mod' on their mid size cars starting in 70 on cars that had factory sway bars (A-bodies had a 4-link similar to mustangs). The sway bar just connected to the lower control arms and didn't connect to the frame at all.
    I may have to grow old but I don\'t have to grow up!

    What size plate did you use to box them? I'd like to do this to my car soon.

    Is there any measurable advantage/disadvantage to boxing the upper control arms? I recently boxed the lowers and was thinking, why not box the uppers as well? I searched around the forum but didn't find any talk of this one way or the other...

    I heard that if you box the uppers that it would cause binding, but im not 100% sure.

    ------

    But I forgot to post my LCA's, I finished them about 2 months ago.

    First, I got the LCA's off of a PI because they are made of 12 gauge steel, instead of 14 gauge civi ones, so they are already stronger than my factory ones. Then I fully boxed them with 3/16" diamond plate steel.

    I haven't gotten around to installing them yet, but I can't wait to see the difference.
