1. The stabilizer absorbs sudden impact forces of the steering. If you hit something, the load from the tie rod is transferred to both the center link and the stabilizer instead of being transferred into the center link and the tie rods.
2. Bent components are fine if they are ran at the correct angles and are not molded out of cheese. Note that the pitman arm and idler arm are not straight on the factory setup either.
Yes, the further inward holes are the reason for the new inner tie rods. Also, those new inner tie rods allow for up to 90 degrees of travel! The dog-bone style link inner tie rods will only travel up to about 45 degrees. You have a lot more travel with the 2WD center link so I doubt you will ever be bending those tie rods. I'm going to mount the system next week and see how it holds up.
