F/R adjustable slipper?

[joffacn]

Hi
This quote from Jeremy on the RCTech forum:
"My car had the new parts on it that will be in the Worlds/Japan kit that will be released soon. The new front arms, front bumper, new style slipper that can slip f/r equally or f/r individually, inner ball stud mounts, thinner rear swaybar, new shocks, lowered wing mounts I think is all or most of what will be new/different."

Does anyone have info on this Slipper? I saw that they had a Slipper with External adjustment but how does that translate to F/R equal OR F/R individual? It only has one adjustment collar.

Is this Slipper another Option? Any good pics or info?
