Advantages of aftermarket upper:lower control arms
Advantages of upper/lower aftermarket control arms except more adjustment
During alignment
Which ones are good yet not a lot of $$$
The adjustable tube uppers are a waste if your not full on racing. And with heim joints there’s no deflection like with a rubber / poly bushing, this adding wear to the heim which are replaced often on race cars. The non adjustable are built with tube like stock style mounts / bushings and have extra caster built into them (most of the time) and will get you to where the car wants to be for it alinement.
As for the lowers, I think that stock LCA with reinforcement mods done are better then the tube lowers.
Adjustable strut rods are a waste if your not full out racing. Would get the heavy duty ones though..
The best thing is to ask yourself what are you going to do with your car. And then build it to the way the car is going to be used.
For my 72 duster, I’ve built it for heavy canyon carving / auto cross. I have FirmFeel tube UCA, reinforced LCR, 1.06 T-bars, front and rear sway bars, heavy duty rear springs and upgraded brackets/ hardware with frame connectors / torque boxes. I’ll tell it planted and handles corners very well for being old school; but is different than how I’m building my 70 duster drag car...
