Advice for coil-over adjustment

[1962nova]

I recently got my car up and running after 5 years, and have put about 50 miles on the car so far. The car is a 62 nova, Total Cost Involved front Coil Over IFS/4link with coil overs. Still need to get the car alligned and put the front sway bar on, but my question is about the coil overs.

They are single adjustable All-American coil overs (TCI's brand made by someone else). I have all of the knobs at the 3 click on the adjuster (1 being the lowest, 12 the highest) It rides smooth and doesn't bottom out.

Are these mostly for ride comfort or for performance too? If so, how is everyone adjusting them to get the most of their suspension? How should they be set, and what should I be looking for in driving characteristics when adjusting them?

Thanks,

Kent
