About StopTech Sport Cross-Drilled Disc Brake Rotors

The StopTech Sport Cross-Drilled Disc Brake Rotors line is designed to offer enhanced braking performance through advanced rotor surface technology. The cross-drilled pattern improves ventilation and helps dissipate heat more efficiently during aggressive driving or heavy braking conditions. These rotors feature a vented design with straight vanes to maintain consistent cooling, while the coated hat finish protects against rust and corrosion. This product line is suitable for drivers seeking a balance between everyday usability and improved brake response.

Technical Details and Compatibility

Part number 128.47018R is specifically compatible with several Saab and Subaru models, including the Saab 9-2X and Subaru models such as the Baja, Forester, Impreza, Legacy, and Outback. The rotor features a 5-lug configuration with a 100 mm bolt circle diameter and a center hole diameter of 2.283 inches (58.000 mm). The floating disc mounting system allows for slight movement to reduce stress and improve rotor longevity. Weighing approximately 14 lbs (6.360 kgs), this rotor balances durability with manageable weight for improved vehicle dynamics.

Common Applications and Problem Solving

• Reduces brake fade during extended or aggressive braking
• Improves heat dissipation to prevent rotor warping
• Minimizes corrosion with coated hat finish for longer service life
• Enhances braking consistency on Subaru Forester, Impreza, Legacy, Outback, Baja, and Saab 9-2X
• Addresses uneven rotor wear and vibration issues

Installation Notes and Tips

Ensure compatibility with your vehicle’s make and model before installation. The rotor requires a 5-lug wheel hub with a 100 mm bolt circle diameter. Proper torque specifications should be followed when mounting the rotor to avoid warping. Since this rotor does not include bearings or an ABS tone ring, verify that your vehicle’s existing components are compatible. It is recommended to replace brake pads simultaneously to maintain optimal braking performance.
