3-link? dirt and road guys need input.

I fully understand anti-squat, roll steer/angles etc. My question involves what dirt guys call a pull bar, torque absorber. It seems to be a link that replaces the top link and is telescopic with bushings and it spring. It extends under acceleration to use the differntials torque reaction on the tires increasing traction in a straight line or out of a corner. Under braking it supossed to ease brake hop. The effective instant center would not change so how well can it reduce brake hop. At ride height the lower links on a road car are typically mounted level as a compromise between max anti-squat and roll steer. Shorter links would increase abilitiy to get max anti-squat but would induce brake hop. In a torque arm setup you can decouple the front of the torque arm and use a similar upper link to stop rotation under braking which lengthens instant center under braking clearly reducing brake hop. Without the front pivot of upper Link droping ic cant change enough under braking to effect much. So the reasonble solution would be to run longer links all around again decreasing traction by lowering anti-squat. Thank for the help just look for some theoretical answers I haven't figured out yet.

The tourque absorber takes the shock of the suspension loads cushioning the reaction,However with to steep an angle brake hop can occur. The solution is add 1 more link angled uphill.The way it is arranged is the link angled down hill is in tension upon acceleration and under no pressure upon braking.The opposite occurs under braking the uphill angled arm transmits the forces to the chassis and the down hill angled link is under no force.
