My question is.Would'nt it tighten up the car more if you took the spring off the bird cage and put it on a clamp bracket on the LR?
This way you could keep your bar angles lower and get the same effect through the pinion angle rotation upward via the torque arm under acceleration which in turn will lift or drive the left rear through the spring.This way you would eliminate some of the excess rear steer and extreme rigidity of riding on the links instead of the springs
which are usually unloaded at that point. You could increase or decrease this affect by the length of the clamp bracket and spring rate.The further forward the clamp bracket from the center line of the rear end housing the more lift or load it places on the left rear.You would also have the benefit of the give of the spring under rough track conditions.

yes, it would tighten the car up.
i have run the clamped lr on my late model and found it to be (obviously) very responsive to throttle application and hard to drive, particularly if the track was slick and/or rough.
the lr clamp can actually produce a heap or roll steer if there is plenty of traction to be had on the race track because it will push the rear end way out when on the gas.
i switched to the lr spring behind/shock in front setup and found it much more progressive to drive (feel), not quite as abbrupt, which made it easier for me to drive. but that is just me.

Did you change your bar angles when you clamped? Did you change the spring rate at the left rear or did you just clamp it?Dman

we ran less bar angle on the top rods and lower rods pointing down slightly. we also ran a slightly stiffer spring (25lb) than we did with the unclamped but not as stiff as our current shock behind.
if there is drive in the track, clamped up will get hold of it but be kind to the throttle peddle.
