QA1 Street Performance lower control arms are built for vehicles used mainly for cruising and longer drives. They are configured for QA1 Pro Coil systems with a double shear lower mount. High strength tubing paired with billet aluminum cross shafts keeps the arms among the lightest available while improving strength and durability. The arms are robotically welded and powder coated. Polyurethane bushings isolate road noise for a smoother ride while staying firm enough for good handling, and a high quality integrated ball joint that is stronger than the factory unit is included for long service life. Used together as a set the arms add about 3 to 4 degrees of caster and 0.5 to 1 degree of negative camber; used individually they add roughly half of those figures.
