    Contemporary with billet bottoms and pin drives. Pictured Interesting bottom wish bones. I guess they where like yours Kev?

    Have you modified the flat mounting plate between the chassis for the diff mount .

    Poorly configured radius rods. That set-up will bind.

    10/10 for the observation


    Now have another look at that forward facing radius rod with
    those rose bearings either end.
    What is going to happen?
    BINDING

    Jag diff is solid mounted to the Cobra chassis
    Bottom arm pivots on 4 needle roller bearings.
    because the arm-to-diff relationship needs to be rigid
    in every axis except the vertical.

    It's basic suspension geometry really.

    As the suspension compresses or extends over our speed bumps
    the trailing arm end travels in an arc.
    This effectively pulls the bottom arm forward on any vertical movement
    of the bottom A arm and causes binding.

    Now..... have a good look under your car or have/pay a mechanic do it
    and check.
    Check that those 2 tapered bolts that hold the A arm to the diff are not loose.broken
    or there is play in the IRS!

    The photo I set shows two radius rod mounted at the top so the geometry is a lot better than the 90 deg radius rod. I wonder how effect my Dax ones are as they are at a angle which is not as bad as at 90 deg but still would be still working in an arch through vertical movement.

    This is an interesting site
