QA1 Street Performance control arms are a direct upgrade for vehicles used for cruising and longer drives. Polyurethane bushings isolate road noise for a smoother ride while staying firm enough for good handling, and the integrated ball joint is stronger than the factory unit for long service life. High strength tubing and billet aluminum cross shafts make the arms light yet durable, and the double shear lower mounting is configured for QA1 Pro Coil systems. The arms are robotically welded and powder coated, and when used together they add roughly 3 to 4 degrees of caster and 0.5 to 1 degree of negative camber.
