Ultra Racing 2-Point Rear Lower Brace – BMW M3 F80 / M4 F82 – URKR-RL2-3014
The Ultra Racing URKR-RL2-3014 is a 2-point rear lower chassis brace designed for the BMW F8x M platform, covering both the F80 M3 and F82 M4. Mounted beneath the rear of the car, it links structural mounting points across the lower chassis to provide additional support around the rear suspension and subframe area.
Under acceleration and cornering, substantial loads are transferred through the rear structure of the F80 M3 and F82 M4. Reinforcing this area helps reduce unwanted chassis movement and gives the rear suspension a more stable foundation to work from, particularly on cars running uprated suspension, aggressive alignment settings or higher-grip tyres.
The 2-point layout provides targeted reinforcement without altering spring rates, damping or anti-roll bar stiffness. This makes the RL2-3014 a useful supporting modification for road, fast-road and track-focused builds where improved chassis consistency is the priority.
