The QA1 52518 pro-touring control arms are built for autocross and road course handling. They use the QA1 Ultra Low Friction ball joint to eliminate flex and provide bind-free movement, and they are configured for QA1 Pro Coil systems with double-shear lower mounting. High-strength tubing and billet aluminum cross shafts keep the arms light while improving strength and durability, and they are robotically welded and powder coated. Used as a set the arms 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. The one inch longer upper ball joint stud improves camber gain to keep the tire contact patch optimal for cornering grip.
