Does anyone have any knowledge/opinion on how much "rotating" load a rack can tolerate?

I have a T-Bird power rack/new that I`m installing in a project and I can`t mount the rack high enough because of the engine.
So I have "off-set" the inner tie-rods up and forward 1-1/4" with and adaptor. They will be connected to each other with a link.

I see that some of the UNISTEER kits as well as some other brands do this too,however some have rollers to support the link between the inner rods,and some don`t.

So what I would like to know is can/will a rack tolerate the load being off-center unsupported??
