I helped a buddy install the hr parts and stuff bar in his Malibu and they told us to install the driver's side link then have the car the way it will be raced with the driver sitting in it then get the pass. side bolt to slip in with no resistence, bolt it in then lengthen it half a turn. That's preload on that side. It should work neutral to a small amount of preload. The TRZ guys are very helpful and they can tell you whether to shorten or lengthen the pass side link if the car goes left or right. I could probably remember if I hadn't been working in the 100 deg. heat and my brain is in overload.
