Ultra Racing 4-Point Rear Lower Brace – Audi A1 / S1 8X – UR-RL4-1834
The Ultra Racing UR-RL4-1834 is a 4-point rear lower brace designed for the Audi A1 8X platform, with fitment listings also supporting the Audi S1 8X. Mounted beneath the rear of the car, it reinforces the lower chassis structure by connecting several key mounting points across the rear floor and member area.
Its 4-point layout gives the brace a broader area of support than a simple 2-point bar. This helps spread forces through the rear structure when the car is subjected to cornering, braking and uneven road loads, making it a useful addition for A1 and S1 builds running firmer suspension or higher-grip tyres.
The RL4-1834 is particularly suited to drivers looking to strengthen the rear section of the chassis without changing spring or damper characteristics. It can also form part of a more comprehensive Ultra Racing setup alongside front lower braces, strut bars and centre chassis reinforcement.
