StopTech 128.34089 Sport Cross-Drilled Brake Rotor - Front Right 345x28mm

StopTech part number 128.34089 is a front right Sport Cross-Drilled brake rotor engineered as a direct OE replacement disc. Part of StopTech's 128-series SportStop line, this rotor delivers a meaningful performance upgrade over stock while retaining full compatibility with factory calipers and brake hardware.

Key Features:

• Cross-drilled design aids heat dissipation and brake dust dispersal, prevents pad glazing, and adds bite for improved wet and dry braking performance
• Black e-coating applied electrostatically to the hat, cooling vanes, and outer edge — engineered to withstand 400+ hours of salt-water exposure for superior corrosion resistance
• High-carbon metallurgy with added Molybdenum and Chromium for quieter operation, better crack resistance, and enhanced overall performance
• 100% fully machined finish including the rotor hat for improved balance and a clean, precision appearance
• Mill balanced to a tolerance of less than 2 oz-inch, reducing vibration feedback for a smooth, confident braking feel
• Directional cooling vanes act as a more efficient air pump compared to straight or pillar OE vane designs, increasing airflow and resistance to brake fade
• Center-split core casting promotes proper heat transfer and thermal efficiency
• Direct OE replacement — retains factory calipers with no modifications required

The StopTech 128.34089 is an ideal upgrade for performance-oriented street driving, offering race-proven technology in a bolt-on package. It pairs especially well with higher-friction, European-style brake pad compounds.
