StopTech 121.47032 Sport Cryo-Treated Blank Brake Rotor

The StopTech 121.47032 is a sport-grade, cryogenically treated blank brake rotor engineered as a direct OEM-style replacement with enhanced durability and performance. StopTech's cryogenic treatment process stress-relieves the iron casting at the molecular level, resulting in a harder, more wear-resistant rotor surface that extends service life and reduces the risk of cracking under repeated thermal cycling.

Key Features:

• Cryogenic Treatment: Deep freeze processing relieves internal casting stress for improved durability and longer rotor life
• Blank (Non-Slotted/Non-Drilled) Face: Smooth double-disc ground braking surface for consistent pad contact and reduced pad wear
• Corrosion-Resistant Coating: E-coat or zinc wash finish protects the hat and non-swept areas from rust and corrosion
• Direct-Fit Replacement: Engineered to OEM dimensions for a bolt-on installation without modification
• Premium Metallurgy: High-grade iron alloy formulation minimizes brake squeal and maximizes thermal performance
• Vented Construction: Internal vane design promotes airflow and heat dissipation during heavy braking

StopTech is an industry leader in high-performance braking systems, manufacturing all components to ISO standards at their Southern California facility. The 121.47032 rotor is an excellent upgrade over worn or standard factory rotors, delivering improved stopping confidence and long-term reliability.
