Shock absorber opinion
get the springs right first.
Torsion and leaf. I forgot to mention I upgraded to the 1.03 from PST and would consider them the baseline of TB’s for modern radial tires. If you are using a 14” wheel or a skinny front tire (drag or cruiser) then sub-1” bars would be sufficient but if you have a 15” wheel with say, 225/60-15 and take cloverleafs aggressively or like your car to handle then 1.03’s would be my choice. Get a sway bar too.
Of course, cars are made of components that fit within systems. A car is a multitude of components within systems that are dependent on each other. Even if your budget calls for high or low quality you should approach purchases of these components in that mindset. How will it work with where I want to go? Will this work toward my goals?
The foundation of your suspension is springs (tb and leaf) Start there unless you have leaking blown out shocks. Shocks I consider secondary. Finally, sway bars and other traction aids. Plan it out and build ground up. Springs, shocks, aides.
