Overview

The Ultra Racing UR-RS4-2629P is a 4-point rear lower bar designed to enhance the chassis rigidity of your vehicle. It combats chassis flex and deformation caused by weight transfer during cornering, braking, and acceleration. By reducing flex, this bar helps maintain tire grip and improve handling traits like understeering and oversteering.

Show original supplier description

The Ultra Racing 4-Point Rear Lower Bar (UR-RS4-2629P) is engineered to significantly improve the structural integrity of your vehicle's chassis. The car's chassis undergoes considerable stress from weight transfer during dynamic driving maneuvers such as fast cornering, hard braking, and aggressive acceleration. This stress can lead to chassis flex and body deformation, causing tires to lose grip and resulting in undesirable handling characteristics like understeer and oversteer. The hollow steel tubes and oval tubes used in its construction range from 1.2mm to 1.6mm in thickness. Ultra Racing's commitment to quality is underscored by rigorous testing of all raw materials. Ultra Racing braces bolt directly to existing chassis points, typically allowing for installation in 30-60 minutes with basic hand tools. The product is specifically designed for the Toyota Corolla Altis (E170) 1.8/2.0 2WD models from 2013 to 2018. The product page explicitly states "This product DOES NOT FIT for your" if a vehicle is not compatible, ensuring clarity on fitment.
