Probably rear cradle bushings.
I forget his username here, maybe TRZ06... he changed his SS 1LE rear cradle bushings to the solid ZLE mounts and has said these things go away, I notice that wiggle cornering over broken pavement and quick l-r steering inputs. I'm pretty sure ZL1 and SS 1LE rear ends are the same.
