Mazda RX-8 Sway Bar - Rear - Whiteline - 18mm Heavy Duty, 2-Point Adjustable ('03–'12). This Whiteline rear sway bar is designed to reduce body roll and improve cornering balance on 2003–2012 RX-8 models while retaining everyday ride comfort.

Engineered to transfer lateral loads more evenly across the tires, this 18mm heavy duty blade-type bar gives firmer roll control and more predictable mid-corner behavior. The two-point adjustable mount lets drivers fine-tune rear roll stiffness to match driving conditions or personal preference. Whiteline uses durable synthetic elastomer mounts with internal grease reservoirs and grease-retention features for long-term, low-friction operation. Protective powder coating and anodized alloy components resist corrosion and wear, and forged ends and DIY lateral locks maintain alignment and strength where the links attach. A comprehensive install guide is included and the kit ships with extreme-pressure molybdenum disulphide (LM) grease for initial lubrication.
