4-Point Rear Lower Bar

The Ultra Racing 4-point rear lower bar (URTH-RL4-4047) is engineered to significantly enhance your vehicle's chassis stiffness and overall handling performance. It directly addresses the chassis flex and twisting that occurs under load during aggressive driving maneuvers like cornering, hard braking, and acceleration. By minimizing this flex, the bar helps to maintain optimal tire grip and prevent undesirable handling characteristics such as understeer and oversteer, leading to a more controlled and confident driving experience. The structural tubes are made from durable steel, with thicknesses varying from 1.2mm to 1.6mm. These materials are chosen not only for their strength and rigidity, which preserve consistent geometry, but also for their ability to crumple safely during an impact. The raw materials undergo rigorous testing to ensure satisfactory performance and reliability. This hands-on approach allows for continuous product enhancement and feedback accumulation from demanding motorsport environments. The brand is a proud chassis tuning partner for various racing teams, underscoring its credibility and performance in competitive motorsports. This specific rear lower bar is designed for direct fitment on the BMW 5 G30 (530E) 2.0T 2WD Electric Motor models from 2017 onwards. Installation is straightforward, offering a significant suspension enhancement without requiring extensive modifications.
