Tom,
As you may know, I run QA1 "R" series coilovers (w/BB springs) and Global West upper and lower control arms on the '70...along with 2nd gen ('78) Camaro spindles.
I never really have to adjust them. Once I got the ride height set, all my tuning between the street and track is at the shock settings.
And, I run a 28" Hoosier skinny on the track...a 235/70-15 (26") BFG TA on the street.
On street tires...
