ST Suspensions Rear Sway Bar - BMW E30 1984-1994

This ST Suspensions 19 mm rear anti-sway bar reduces body roll and sharpens turn-in on the BMW 3-Series E30 (sedan, coupe, convertible) and E30 M3 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. Increasing rear roll stiffness dials out understeer for a more neutral, classic-BMW balance. Made in the USA.
