Detailed Product Description

This StopTech Sport Cross-Drilled & Slotted Disc Brake Rotor features a vented design with straight vanes that promote efficient airflow to cool the rotor during braking. The cross-drilled and slotted surface pattern helps evacuate gases, dust, and water, improving brake pad contact and reducing the risk of brake fade under demanding conditions. The rotor’s coated hat finish offers protection against rust and corrosion, maintaining structural integrity and appearance over time.

With an outside diameter of 301.2 mm (11.858 inches) and a nominal thickness of 26.3 mm (1.035 inches), this rotor is designed to fit a range of GM vehicles including Buick LeSabre, Cadillac DeVille, Chevrolet C1500, GMC Safari, Oldsmobile Delta 88, and Pontiac Bonneville, among others. The 5-lug hole pattern with a 127 mm (5 inch) bolt circle diameter ensures compatibility with factory wheel setups. This rotor does not include an ABS tone ring or bearings, so it is intended for direct replacement on compatible models.

StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors Line

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to provide enhanced braking performance through improved heat management and pad bite. This product line focuses on rotors that feature both cross-drilled holes and slots, which work together to maintain consistent braking under high-stress conditions. The vented rotor design with straight vanes further aids in cooling, making these rotors suitable for drivers seeking reliable stopping power on street and light performance applications.

Common Applications and Problem Solving

• Reduces brake fade during extended or aggressive braking
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust buildup for cleaner rotor and pad contact
• Helps prevent glazing of brake pads for consistent performance
• Addresses corrosion issues with coated hat finish for longer rotor life

Installation Notes and Tips

• Ensure rotor thickness is within discard limits before installation (minimum 0.965 inches / 24.5 mm)
• Compatible with hub and rotor mounting; verify 5-lug wheel pattern and bolt circle diameter (127 mm / 5 inches)
• Check for proper fitment on specific Buick, Cadillac, Chevrolet, GMC, Oldsmobile, and Pontiac models
• Use recommended torque specifications for mounting bolts to avoid warping
• Brake pads should be inspected and replaced if worn to maximize rotor performance
