APR Rear Roll-Control Sway Bar VW/Audi (AWD MQB/MQB EVO Haldex) | SUS00036

The APR Rear Roll-Control Sway Bar (SUS00036) is a critical suspension upgrade for AWD MQB and MQB Evo vehicles equipped with the Haldex-based all-wheel-drive system. By increasing the bar diameter to 25mm with a 5mm wall thickness, APR delivers up to a 95% increase in spring rate over the factory MK7 Golf R bar. This increase in rear roll stiffness helps combat the inherent understeer characteristic of AWD platforms, allowing for better rotation and flatter cornering during spirited or track driving.

Constructed from high-tensile hollow steel, each bar is CNC-bent from a single piece of stock to ensure a superior strength-to-weight ratio and long-term reliability. The bar ends are forge-pressed and quench-hardened for maximum durability, while high-performance polyurethane bushings eliminate the deflection found in factory rubber. Finished in a signature red powder coat, the bar features two-way adjustability, allowing you to fine-tune your chassis balance for either the street or the track.

Key Features:

• Neutralized Handling: Specifically tuned to reduce understeer and improve chassis rotation on Haldex-equipped AWD models.
• Significant Stiffness Gain: Provides up to a 95% increase in spring rate over the factory MK7 Golf R rear bar.
• Two-Way Adjustability: Features multiple end-link mounting points to select between Soft (611 lbs/in) and Stiff (697 lbs/in) settings.
• Premium Hollow Steel: 25mm diameter design provides maximum stiffness while keeping unsprung weight low.
• Unrivaled Strength: CNC-bent from a single bar with no welds; forge-pressed and heat-treated ends for maximum reliability.
• Polyurethane Bushings: Includes upgraded bushings to ensure immediate suspension response and zero bar movement.
• Direct Bolt-On: Precision-engineered for a perfect fit as a direct replacement for the factory rear stabilizer bar.
