Looking for even better suspension performance after installing coilovers or lowering springs on your BMW? H&R sway bar kits are made of high tensile strength (hf) 50CrV4 steel alloy that produces reduced roll response time and increases cornering stiffness over stock. Larger diameter, stiffer sway bars increase lateral stability and reduce body roll, which improves cornering grip. H&R sway bars are cold-formed and heat treated with seamless, no-weld end flanges. Shot-peened for lifetime durability. To finish off these great sway bar kits, they come with new urethane/teflon composite bushings that won't squeak or need lubrication. The best sway bars, and best sway bar brands for BMW are available at MGC. Images shown are for illustration only and may not be the bar(s) for your Z4.
