4-Point Rear Lower Brace

The Ultra Racing 4-point rear lower brace (URVN-RL4-4298) is engineered to significantly reduce vehicle chassis flex, a common issue exacerbated by weight transfer during aggressive driving maneuvers like cornering, braking, and acceleration. The steel plates used for the mounting brackets are between 4mm and 5mm thick, providing robust support. The structural steel tubes, including hollow and oval profiles, range from 1.2mm to 1.6mm in thickness. Ultra Racing selects these specific material gauges to achieve optimal rigidity and strength, crucial for maintaining consistent vehicle geometry. Importantly, the design also incorporates a safety feature allowing the brace to crumple upon significant impact, mitigating damage to the chassis. The chassis of a vehicle is subjected to considerable stress, especially during dynamic driving. During hard cornering, one side of the vehicle can endure forces up to three times greater than the other, leading to chassis flex, deformation, and a loss of tire grip. This deformation can manifest as negative handling traits such as understeer and oversteer. The Ultra Racing rear lower brace directly addresses these issues by reinforcing the chassis structure, particularly by connecting to the lower wishbone suspension components. This reinforcement helps neutralize the shock of impact and prevents undesirable chassis movement, leading to improved stability and handling response. Ultra Racing’s products have a proven track record in motorsports, including Time Attack, drifting competitions, and track racing. This involvement allows them to gather valuable feedback and continuously enhance their designs. The brand serves as a chassis tuning partner for various motorsport teams, demonstrating their commitment to performance and reliability.
