    Narrowing a C4 IRS....Wow....my head hurts!

     



    I can't tell you all my worries with this C4 IRS. LOL's. But I think I can...I think I can.

    Who on here has done the C4 IRS set-up on thier street rods? I did a search in the photo gallery but I'm still having trouble.

    What angle do I need to set the frame bracket for the dogbones? 55 degrees looks like it will still allow plenty of suspension travel (3.5" or so).

    How narrow have you guys gone? I was thinking about making a 1" spacer between the differential and the cover, which would move the batwing back 1" and narrowing the rearend 6" over-all. I would still have to hog out a small portion of the hubs (knuckles) to clear the batwing....but not much with the spacer added.

    I could really use some help here. I'm about to ditch it and opt for a nine inch. I dont usually give up this easy...but man my head hurts.

    I've got another thread similar but this one isnt really about alignment....please dont burn me.
