I installed a set of Tein S-Tech springs a few weeks ago. I figured they should be broken in by now, so I took my baby in for an alignment. Anyway, They said they got it as close as they could, but were unable to get it within spec. From what I can gather, both rear wheel toe is within spec, but the camber is .1 out of spec. The front wheels are in spec with toe and caster, but out of spec on camber same as the rear. I thought I read that with the small drop of the Tein springs, the Z could be put back within spec. Plus, with the # of times Nissan keeps changing the alignment specs, how do I know they used the most current setup?
