This alters the percentage of loading caused by mass of the vehicle on the rear tires during acceleration. Some circle track cars use this principle (moving the 4-link pick-up) to load the outside rear tire during acceleration. Most use a full floating rear end which, in effect, stops the rotational forces from transfering through the four link, much like an IRS.

exactly.. so its only the "lift" caused by "pushing" on a non horizontal pair of links.... so the antisquat effect is caused by the thrust acting over or under the C or G..
