Ultra Racing 23mm Rear Anti-Roll Bar – BMW M3 E90 / E92 – URTW-AR23-485
The Ultra Racing URTW-AR23-485 is a 23mm solid rear anti-roll bar developed for the BMW E9x M3 platform, covering both the E90 Saloon and E92 Coupé. Designed to increase rear roll resistance, it helps reduce excessive body movement through corners and can sharpen the way the rear axle responds during faster changes of direction.
On the E9x M3, the rear suspension plays a major role in how the car balances under throttle and cornering load. Increasing rear roll stiffness can help the chassis feel more responsive and controlled, particularly on cars running performance tyres, firmer suspension or more track-focused setups.
Unlike a chassis brace, the anti-roll bar directly influences suspension behaviour. The 23mm solid construction works to resist the difference in movement between the left and right rear wheels during cornering, helping the car stay flatter and giving the driver a more immediate sense of rear-end control.
