After market control arms?

Right

$273 and $235 each. Eeash. Expensive upgrades. But I’m sure worth it

Er.... the stock rear arms have camber and toe adjustment.
Sure, they're stamped steel and not tubular, but an adjustable front lower arm is more important.
All-out track guys may have some use for the adjustable rear uppers, but more likely to just cause problems.

Are the adjustable rear uppers on the front suspension? As I would love to adjust the caster, makes it more stable and you get camber as a bonus when turning the wheel.
