Other than the FSM alignment specs, are there recommended settings for greater high speed stability or better handling for an early 260Z?  The suspension on my car has stock springs, Bilstein inserts, heavier anti-sway bars, front and rear camber adjustment kits, t/c rod kit and adjustable t/c rods.  The car will only be used on the street.

Thanks.

Do these settings apply to a 260Z with 205/60-15's?

As noted they're starting points and you as the driver need to provide input after the suspension has been set. Have  an alignment shop dial in the settings, drive it and tell them what the car did or didn't do.

If you can't feel any differences then you might want someone else to drive the car in a controlled manner and get feedback from them, make changes and see how it feels to you.
