Product Description

The Whiteline BTR86Z Rear Sway Bar is a chassis-specific handling upgrade for 2006-2012 Toyota Yaris and 2008-2011 Scion xD models. By replacing the small factory rear bar (or adding a bar where none was fitted), this 22mm solid bar sharply reduces body roll and keeps the rear of the car flatter in corners. The result is more even tire loading, improved rear grip, and a more confident feel when changing lanes, attacking on-ramps, or driving spiritedly on back roads.

With a 2-point adjustable design, the BTR86Z lets you tune rear roll stiffness to match your springs, shocks, and driving style. Softer settings retain a comfortable street balance, while stiffer settings increase rotation and response for autocross or track days. High-quality spring steel, polyurethane bushings, and a durable powder-coated finish ensure long service life even in harsh climates. Because the kit is engineered specifically for the Yaris and xD beam-axle rear suspension, installation is a straightforward bolt-on upgrade, making this one of the best dollar-per-lap and dollar-per-mile handling improvements you can make to these compact platforms.
