    Default Raising lr lower bar

    What would a guy expect if he raised the lr lower four bar up equally on both ends? So up closer to rear end on birdcage side and the same amount up on chassis?

    17" LRU at 25 degrees
    15" LRL at 10 degrees
    STD 4.5" up from center of axle

    Static thrust = 17.81 degrees

    dynamic at 4.4" of drop at cage

    Thrust = 36.66 degree's
    Index of cage = 10.05 degrees
    2.274" of forward movement of cage / rollsteer

    With LRL bar up 1" on cage to 3.5" below axle centerline - frame end also moved up 1"

    Static = 16.87

    Dynamic 4.4" of drop at cage

    Thrust = 35.70 degree's
    Index of cage = 11.40 degrees
    2.170" of forward movement of cage / rollsteer

    like above and to my point the index of the cage is faster

    Ok. So with it acting faster would you see an increase in traction or would you just feel it all happen sooner?

    I would be careful moving the birdcage end up. I know we already have to run a bent bar on the LR lower for clearance. I’ve never moved that end, but definitely run it through it’s motion to be sure.
