So what can we do about eliminating axle hop?

If there's one major platform disparity, it's that fact that F-bodies have to drive and brake bias around rear axle hop while the ford guys can actually use their rear brakes and go fully aggressive with brake compound.

If I understand correctly it can be as simple as converting the nose end of the torque arm to be a sliding type instead if a fixed bushing with no other geometry changes.
