APR Roll-Control Sway Bar – Rear – (AWD MQB/MQB EVO RS Diff/Torque Splitter) – SUS00031

APR Roll-Control Sway Bars are engineered to significantly improve cornering performance by reducing vehicle body roll without greatly impacting comfort. Drivers who enjoy a more spirited driving style often encounter excessive body roll, which negatively impacts handling. During cornering, the vehicle’s body leans to the opposite side, shifting weight primarily to the outside tires. This uneven distribution reduces grip on the inner tires, resulting in decreased overall traction and stability.

Our solution? APR Sway Bars are fine-tuned with an optimized spring rate achieved through increased bar diameter and strategic placement of end-link mounting points forged from a single bar. Additionally, we upgrade the bushings to high-performance polyurethane, eliminating bar movement and compression during hard turns, ensuring consistent and enhanced performance.

APR Sway Bars are designed as a direct replacement for your factory-installed bars. Simply swap out the original bars with our upgraded sway bars to experience improved handling immediately. Whether referred to as stabilizer bars, anti-roll bars (ARB), or sway bars (FSB/RSB), APR’s bars deliver superior cornering control and driving confidence.

Getting Technical:

APR Sway Bars are constructed from high-tensile strength steel, known for its excellent durability properties. To reduce weight without compromising strength, these bars are hollow. Each bar is precision CNC-bent from a single piece of bar stock, eliminating welds and significantly reducing the risk of failure compared to traditional manufacturing methods. The bar ends are forged into shape and then quench-hardened in specialized fixtures to achieve the highest strength profile possible, and then dimensionally confirmed in final check fixtures. Lastly, each sway bar is coated with a corrosion-resistant red powder coat, offering both durability and a sleek appearance.

On this particular model, we’ve increased the bar diameter to 25 mm, with a 5 mm wall thickness, an upgrade from the factory’s 22.2×4.3 mm (MK8 R/8Y RS3) size. This enhancement results in a spring rate of 583 lbs/in on the soft setting and 672 lbs/in on the stiffer setting, delivering a 49%/72% increase over the factory MK8 Golf R / 8Y RS3 bar. These changes translate to significantly improved handling, reduced body roll, and a more responsive driving experience.

Optimize your vehicle’s performance with APR’s precision-engineered sway bars for superior strength and reliability.
