ST-22 Rear Big Brake Kit

The StopTech ST-22 Rear Big Brake Kit offers a significant upgrade for performance-oriented vehicles, providing a supercar look and feel. This kit is engineered to surpass stock braking capabilities by increasing heat capacity with larger 328x28mm slotted rotors, thereby reducing the chance of brake fade during hard, repeated stops. Additionally, the kit incorporates stiffer ST-22 calipers and braided stainless steel brake lines, which collectively minimize system compliance. This results in a more consistent, confident, and responsive pedal feel, empowering the driver with enhanced control. StopTech's design philosophy emphasizes a Balanced Brake Upgrade, ensuring that the increased braking resources are precisely apportioned between the front and rear axles to account for vehicle weight transfer. This approach prevents the common issue of brake upgrades adding excessive front torque, which can diminish overall performance by limiting the traction available from all four tires. The ST-22 calipers are fully forged and 2-piece, known for their minimal flex and deflection due to a patented bolt-in bridge. They are finished in a glossy, high-temperature red paint. The kit also includes StopTech Street Performance Brake Pads, suitable for high-performance street driving and light track use, featuring para-aramid composites for linear response and a low-dust formulation. Installation is facilitated by application-specific hardware, including hard anodized 6061-T6 billet aluminum mounting brackets with stainless steel studs, designed for precise fitment and strength. This kit is specifically designed for the 2000-2002 Audi S4 Base and Avant models.
