4-Point Rear Lower Bar

The Ultra Racing 4-point rear lower bar (URTW-RL4-4021) is engineered to enhance the structural integrity of your vehicle's chassis. During performance driving, the car's chassis is subjected to significant stress from weight transfer during cornering, braking, and acceleration. This stress can lead to chassis flex and twisting, negatively impacting handling by causing understeer or oversteer and causing tires to lose grip. This rear lower bar is constructed from aluminum and features a 4-point design, providing increased rigidity to the rear of the vehicle. By bracing the chassis, it helps to stabilize weight transfer between the front and rear, thereby reducing body roll and improving overall handling characteristics. The direct-fit design ensures installation without requiring modifications, utilizing original mounting points. This specific Ultra Racing rear lower bar is confirmed to fit the Infiniti Q70 (Y51) 3.5 V6 4WD models produced from 2013 to the present. Its installation is straightforward and contributes to a more connected and responsive driving experience by minimizing chassis flex.
