• Floating disc mounting for better rotor alignment and reduced warping
• Compatible with 5-lug wheel configurations and 10.5-inch (266.7 mm) outside diameter

Product Line Details: StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line focuses on performance-oriented rotors that combine cross-drilled holes and precision slots. This design enhances braking efficiency by allowing gases and debris to escape while maintaining rotor structural integrity. The vented construction with straight vanes improves airflow, reducing heat buildup during aggressive driving or towing. This rotor line is suitable for drivers seeking a balance between everyday use and enhanced braking response on vehicles like the Buick Riviera and Oldsmobile Toronado.

Technical Specifications and Features

These rotors feature a nominal thickness of 1.035 inches (26.3 mm) and a discard thickness of 0.957 inches (24.3 mm), ensuring a durable braking surface throughout their service life. The overall height measures 2.047 inches (52 mm), and the center hole diameter is 2.783 inches (70.7 mm), designed to fit specific GM wheel hubs. The mounting bolt hole circle diameter is 4.748 inches (120.6 mm) with five lug holes sized at 0.524 inches (13.3 mm). Weighing approximately 14.2 lbs (6.45 kg), these rotors maintain a balance between strength and weight for optimal vehicle dynamics.

Applications and Problem Solving

• Reduces brake fade caused by excessive heat during towing or heavy braking
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust buildup for cleaner wheel appearance
• Prevents rotor warping and uneven pad wear through vented design and floating mounting
• Compatible replacement for worn or damaged rotors on Buick, Cadillac, Chevrolet, GMC, and Oldsmobile models

Installation Notes and Tips

Ensure compatibility with your vehicle’s make and model before installation. These rotors do not include bearings or ABS tone rings, so verify if your application requires these components separately. Proper torque specifications should be followed when mounting the rotor to avoid warping. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. Clean the rotor surface with brake cleaner before installation to remove any protective coatings or residues.
