Rear Upper Strut Bar

The Ultra Racing Rear Upper Strut Bar is engineered to optimize the handling of the 2011+ Toyota Yaris (XP130) models equipped with 1.2/1.5L engines and 2WD. This component directly addresses chassis flex, a common issue that can lead to imprecise handling, reduced steering feel, and compromised safety, especially during dynamic driving maneuvers like cornering, braking, and acceleration. This strut bar is constructed from robust materials, featuring steel plates between 4-5 mm thick and stable steel tubes with a 1.2-1.6 mm wall thickness. These specifications ensure maximum strength and longevity while adhering to international standards such as JIS 3101 SS 400, JIS G 3141 SPCC SD, ASTM A 500 Grade A, and BS 1387. Ultra Racing deliberately chooses steel over aluminum for its superior strength-to-weight ratio at similar thicknesses, ensuring a more stable and rigid reinforcement. The design also prioritizes safety by allowing for controlled deformation in the event of an impact. By reinforcing the rear axle area, this strut bar significantly increases chassis stiffness, leading to a more direct driving feel, improved stability in curves, and enhanced overall control. The benefits extend to increased active driving safety and a more precise steering response. Ultra Racing's commitment to quality is evident in their rigorous testing of all raw materials.
