Alcon BRK.200590 Pro-System Rear Big Brake Kit 4-Piston 355x28mm BMW E46 M3

The Alcon BRK.200590 is a professional-grade rear big brake kit featuring 4-piston calipers and 355x28mm rotors, specifically engineered for the BMW E46 M3. This Pro-System brake kit is manufactured in the USA at Alcon's Mooresville, North Carolina facility, with rotors machined from specially formulated grey cast iron providing optimal thermal stability, friction coefficient, and heat transfer characteristics.

Key Features:

• Forged aluminum calipers constructed from aerospace grade aluminum alloy for high strength and light weight, used in top level pro racing
• CNC machined lightweight 6061-T6 aerospace grade aluminum hats with black hard anodized finish to increase resistance to wear and corrosion
• Dyno-bedded rotors and pads for immediate use with no break-in required
• Fully floating rotor attachment with anti-rattle clips included
• Slotted rotor face pattern improves brake consistency by constantly cleaning the contact surface and dissipating heat generated
• Curved directional slots and vanes for maximum cooling and performance

Complete kit includes high performance brake pads, anti-rattle clips, precision machined brackets, and all necessary hardware. Slotted rotors provide superior advantage over blank rotors in wet or rainy conditions by preventing water films from forming between the brake pad and rotor surface. This race-proven brake system delivers enhanced stopping power, improved modulation, and consistent performance under demanding track and street conditions.
