Got the Nismo aligned today. Spec are camber -2, caster 6, toe zero for the front. The rear is camber -1.7, toe is zero. Raining today, so I can't push it some.
The front suspension does feel freer in it's movement over bumps. Hard to describe, you know it's different, more inline with what you would expect. The road noise isn't any different. Sounds the same. The proof will be when I go back to the track again.
