H&R Sport 25mm Adjustable Rear Sway Bar - BMW 530i / 540i (G30) 2017-2023

Adding rear roll stiffness shifts the chassis balance away from the understeer the G30 carries from the factory, so the car turns in more willingly and sits flatter through a corner, all without changing ride height or spring rate. This 25mm H&R Sport bar has two mounting holes in each forged end, so the stiffness can be set at the softer or firmer position by moving the end link. The bar is cold formed and heat treated from (hf) 50CrV4 spring steel, forged seamlessly at the ends and shot peened. Urethane and Teflon composite bushings are supplied with it and need no lubrication.
