Greetings. A newbie here. Got a '74 260z that races on a 2-mile road course. Average speeds are around 75 mph. Slows to 35 and tops out at 120 or so. The suspension was stock and I'm upgrading all four corners to Pro Shock coil over kits with Tokico adjustable struts, Pro Shock springs (350 fr/250 rear) and ArizonaZcar monoball camber plates all around. I know we can debate specific spring rates and strut brands all day, but won't this get me in the ball park and build enough adjustability into the suspension to have a decent base to work from? Right now it handles like a dog. Many thanks.
