StopTech 320.69002 GCX Cryo-Treated Disc Brake Rotor

The StopTech 320.69002 is a GCX (GeoCast Cross-drilled) disc brake rotor engineered for drivers who demand superior stopping performance and extended rotor life. StopTech's GCX rotors combine a unique GeoCast iron alloy with cryogenic treatment to produce a denser, harder rotor surface that resists warping, cracking, and premature wear.

Key Features:

• GeoCast Iron Alloy: Proprietary iron formulation delivers increased hardness and thermal stability compared to standard grey iron rotors
• Cryogenic Treatment: Deep cryogenic processing relieves internal casting stresses and improves microstructure uniformity for a longer service life
• Cross-Drilled Design: Drilled holes promote rapid heat dissipation, reduce brake fade, and help evacuate gas and debris from the rotor surface
• Corrosion-Resistant Coating: Zinc-washed hat and edges resist rust and corrosion for lasting appearance and performance
• OE-Style Direct Fit: Engineered to match original equipment dimensions for straightforward, no-modification installation
• Balanced Construction: Each rotor is precision-machined and balanced to minimize vibration and pedal pulsation

StopTech GCX rotors are an ideal upgrade for daily drivers and performance enthusiasts seeking a rotor that outlasts standard OEM replacements while improving braking feel and fade resistance. Compatible with OEM-style brake pads and direct-fit calipers.
