The H&R sport rear sway bar for 2008–2013 BMW 128i/135i E82 is a 20mm non-adjustable rear bar that reduces body roll and improves mid-corner stability while keeping ride quality intact. It’s an uncomplicated upgrade to sharpen handling balance. Larger diameter over OE and forged-end construction improve transitional behavior; H&R typically supplies Poly/Teflon bushings with the kit to prevent squeaks and remove lubrication needs.
