4-Point Rear Lower Bar

The Ultra Racing 4-Point Rear Lower Bar is engineered to significantly reduce chassis flex experienced during high-performance driving maneuvers such as rapid cornering, hard braking, and aggressive acceleration. The chassis of a vehicle is subjected to immense stress from weight transfer, which can lead to body deformity and twisting, ultimately compromising tire grip and causing undesirable handling traits like understeer and oversteer. Constructed from solid steel plate, this rear lower bar offers robust support and rigidity. Its surface is powder-coated to ensure a long-lasting, durable finish that resists corrosion and wear. Designed as a non-adjustable component, it provides a fixed and stable reinforcement. This specific bar (UR-RS4-3454P) is a direct fit for the Infiniti Q70 models with the Y51 chassis designation, equipped with either the 2.5L or 3.5L V6 engine, and configured for 2WD, manufactured from 2013 to the present. Its four-point design effectively distributes forces across the rear of the vehicle's chassis.
