This is a good point. Subjectively, the stock parts work and work well. The ride is comfortable in stock suspension cars and usually, they track well and do what you want them to do.
Once you need to make an evasive maneuver or brake hard, that assessment can change. They wallow, sway and roll in extremely non-productive ways.
If nothing else, these cars need new alignment specs as they were originally set up for bias ply tires or really primitive radials.
How about “save your time?” This is the choice that each of us has to make. If you don’t rely on your car for transportation, if you’re comfortable with pressing out ball joints/bushings, etc...yeah. It probably makes sense to refresh the stock components.
Personally, I chose tubular control arms. The uppers provided alignment benefits, the lowers saved a little weight and didn’t require welding in reinforcement plates for higher traction use. QA1 pieces went in without a hitch and saved me a ton of time even if it cost more money, no regrets.
