The QA1 52701 street control arms are an upgrade for vehicles driven mainly for cruising and longer distances. They are configured for QA1 Pro Coil systems with double-shear lower mounting, and high-strength tubing with billet aluminum cross shafts keeps them light while improving strength and durability. Polyurethane bushings isolate road noise for a smoother ride while staying stiff enough for good handling, and the integrated QA1 ball joint is stronger than the factory piece for long service. The arms are robotically welded and powder coated. Used as a set they are designed to add 3 to 4 degrees of caster and 0.5 to 1 degree of negative camber, and about half of those figures when used on their own.
