This ST Suspensions rear anti-sway bar reduces body roll and sharpens turn-in on the 2WD VW Golf VII (Mk7, including GTI) with independent rear suspension and the 2WD Audi A3 (8V), by cutting the load difference between the inside and outside tires through a corner. Cold-formed spring steel, multi-stage quenched and tempered, epoxy/powder coated, with composite bushings. Adding rear roll stiffness dials out understeer for a more neutral chassis. Made in the USA.
