Ultra Racing 4-Point Rear Lower Brace – BMW F20 / F22 – UR-RL4-3465
The Ultra Racing UR-RL4-3465 is a 4-point rear lower brace designed to strengthen the underside of the rear chassis on selected BMW F2x models. Ultra Racing officially lists the brace for the BMW 1 Series F20, while specialist UK application data also supports popular 2 Series F22 models including the M235i and M240i.
Its four mounting points allow the brace to reinforce a broader section of the rear structure than a simpler 2-point bar. This helps spread loads across multiple areas of the chassis as the suspension reacts to hard cornering, acceleration and uneven surfaces, making it particularly relevant to modified cars running firmer suspension or higher-grip tyres.
Rather than changing the suspension's spring or damper characteristics, the RL4-3465 provides additional structural support underneath the car. It can therefore be combined with coilovers, lowering springs, anti-roll bars and other Ultra Racing braces as part of a more comprehensive fast-road or track-focused chassis setup.
