SPC adjustable rear upper control arm for 2016+ Honda Civic lets you make on-car camber changes of up to ±3.0° and is built to remain adjustable for life. The forged steel arm retains OE-style rubber bonded bushings for preserved ride quality and uses a double jam nut to lock camber setting. It's intended to replace the factory arm and provide fine camber control for track use or returning to OE alignment after lowering.
