Overview

The Ultra Racing UR-RL4-390 is a 4-point rear lower subframe brace designed to enhance chassis stiffness and improve handling.

This brace aims to reduce chassis flex caused by vehicle weight transfer during cornering, braking, and acceleration, which can lead to negative handling traits like understeer and oversteer. By strengthening the chassis, it helps maintain precise geometry, improve steering feedback, and enhance overall road handling.

Show original supplier description

The Ultra Racing UR-RL4-390 is a 4-point rear lower subframe brace engineered to enhance your vehicle's chassis rigidity. By connecting key points on the rear subframe, this brace minimizes unwanted flex during cornering and hard acceleration, leading to improved handling and stability. This specific subframe brace is designed as a direct bolt-on component, requiring no permanent modifications for installation. Its four-point design provides a robust solution for strengthening the rear chassis structure. The brace has dimensions of 119cm x 42cm x 14cm and weighs 2.5kg. Fitment is confirmed for the 2004-2008 model years of the Acura TSX and the 2003-2008 Honda Accord CL7 and CL9 models. Please note that while the UR-RL4-390 is designed for these specific vehicles, fitment for other Accord generations, such as the 2013 Accord Coupe V6 or 2018-2022 Accord models, may vary and should be verified independently.
