i went with herb adams 3 way adjustable shocks on my 80 Z. he was the suspension designer for GM and he has his own line of parts. you could make them decent for highway use or agressive for canyon carving, all in a few minutes time. i also installed urathane bushings and end links all around. it was like driving a go kart after i was done. it flew down the straights and carved through the corners like a vette, the car was a blast to drive. man i miss that car!!!!
