H&R Rear 21mm Sway Bar Upgrade - E46 323i/325i/328i/330i

The H&R Rear Sway Bar for the E46 323i/325i/328i/330i is a larger 21mm diameter to provide more leverage to better control body motions and keep the tires planted squarely on the pavement. Three settings allow you to fine-tune the stiffness of the bar. Larger sway bars reduce body roll and weight transfer, improving handling, grip, and turn-in response by making the rear end rotate easier. H&R sway bars fit in the stock locations with the original sway bar links and include H&R's exclusive Teflon-lined urethane bushings that require no grease or maintenance. Adjustable links are available and recommended with coil overs or to improve clearance. BimmerWorld recommends sway bars be upgraded after installing a spring/shock upgrade or coil overs, although it's possible to use this with your stock springs and still get a handling improvement.

H&R sway bars are developed and manufactured in Germany to ISO 9001 and TUV standards from the highest tensile spring steel alloy available. Spring steel has the correct strength, stiffness, and spring characteristics for sway bar use. Purpose-built machines manufacture the bars to exact tolerances to ensure a precise fit and correct operation to ensure improved performance for every application. Each bar is heat treated and shot peened for increased surface hardness and then powder coated for long lasting durability.

This E46 rear sway bar upgrade fits the rear axle. Front and rear sway bars should be upgraded together at the same time.
