Ultra Racing 23mm Rear Anti-Roll Bar – BMW M3 E46 – UR-AR23-361
The Ultra Racing UR-AR23-361 is a 23mm solid rear anti-roll bar developed specifically for the BMW E46 M3. Designed to increase rear roll resistance, it helps control body movement through corners and gives the rear axle a more composed, responsive feel when the car is driven hard.
On the E46 M3, rear suspension balance plays a major role in how the car behaves under throttle and lateral load. Increasing rear roll stiffness can help the chassis feel more alert during direction changes and reduce excessive lean without relying solely on stiffer springs or dampers.
The AR23-361 works directly with the suspension rather than simply reinforcing the bodyshell. Its solid 23mm construction is designed to resist the difference in movement between the left and right rear wheels during cornering, making it a useful upgrade for fast-road, track and performance-focused M3 builds.
