I know the FX is based of a 350z Chaise. I know when you aligh the Z's they have tire wearing issues. There is a special way you need to aligh those cars. You just can stick them on there and aligh .. They have bullitens on how to aligh the Z's , I m just asuming its the same procedure. I don't work on inffinities. I only work on nissans.
What i understand is happening , ( At Least onthe Z cars ) Is after it's aligh'd once you start driving the pressure on the front wheels pulls the toe out , witch casues uneven tire wear, mainly on the edges of your tires. So the vech is suppose to be lifted and claibrated, then adjusted with the toe slightly in. So when you start to drive When it pulls the toe , It pulls it into Spec not Out of it. GL
