QA1 Pro-Touring control arms are built for autocross and road course handling. Each arm uses the QA1 Ultra Low Friction ball joint to eliminate flex and deliver bind-free movement, and the ball joints are adjustable and rebuildable for tuning with different stud lengths. High strength tubing and billet aluminum cross shafts keep the arms light while adding strength and durability, 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.
