For more information, visit www.P65warnings.ca.gov.The APR 370x34mm 6-Piston Front Big Brake Kit is an ultra-high-end braking solution specifically engineered to replace the factory units on the Audi 8V RS3. While the RS3 comes with capable brakes from the factory, the APR system offers a significant leap in thermal management and weight efficiency. By utilizing next-generation billet 6-piston calipers and semi-floating 2-piece rotors, this kit provides a firmer pedal feel, more consistent bite, and the correct brake bias to integrate perfectly with the RS3's advanced ABS and stability control systems.
Every component is focused on high-performance longevity. The rotors feature 72 curved directional cooling vanes to shed heat rapidly during aggressive driving, while the stainless steel caliper pistons act as a thermal barrier to prevent brake fluid boil. Whether you are daily driving or competing in professional racing, the APR system is designed to out-brake and out-last the competition without the noise and harshness common in other racing setups.
Key Features:
- 6-Piston Billet Calipers: Engineered for maximum weight savings and rigidity, featuring stainless steel pistons for superior thermal insulation.
- High-Flow 2-Piece Rotors: Large 370x34mm semi-floating discs with 72 curved directional vanes for optimized cooling.
- RS3 Specific Calibration: Tailored to the 8V RS3 platform to ensure perfect brake bias and seamless factory electronic integration.
- Comprehensive Kit: Includes pre-loaded high-performance street pads (standard replacement size), braided stainless steel lines, and all necessary billet mounting hardware.
- Refined Performance: Optimized for low noise, vibration, and harshness (NVH), making it a premium choice for street-driven RS3s.
- Thermal Management: Features Maximum Temperature Recording (MTR) systems to help drivers monitor brake heat and select the ideal fluids and pads for their usage.
