The H&R Sport sway bar kit for 1990–1991 BMW 318i/318is (E30) matches a 22mm front and 18mm rear bar to reduce body roll and sharpen cornering while preserving ride quality. Built to increase roll stiffness and lateral grip, the kit typically includes H&R’s Poly/Teflon bushings to prevent squeaks and remove the need for lubrication, delivering improved stability with low maintenance.
