Ok so I don’t know if I need adjustable control arms. I plan on using coilovers and drop about 2 inches maybe, do I need adjustable upper and lower controls, or just adjustable uppers? Or just adjustable lowers? Idk or do I even need adjustable control arms.
If you are doing coil overs on all 4 corners, the adjustment in ride height is through the coil over.
If you are doing coil overs up front only, and conventional springs in the rear, then you need adjustable lower control arms with adjustable spring perches to vary the ride height. You don't need them, but it will help you adjust height to match the front.
Adjustable upper rear control arms don't have anything to do with ride height. They are for adjusting how far back or forward the rear axle sits to change pinion angle.
