Technical Description and Specifications

This Dynamite Friction rotor features a solid disc design with a nominal thickness of 11.2 mm and a discard thickness of 9.4 mm, ensuring a clear service life indicator. The rotor’s 278 mm outside diameter and 27.9 mm overall height fit specific GM models requiring a 5-lug bolt pattern with a 115 mm bolt circle diameter. The drilled and slotted surface improves ventilation and helps evacuate brake dust and gases, while the directional pattern optimizes braking efficiency. The zinc silver coating on the hat area provides corrosion resistance, extending rotor life.

Applications and Problem Solving

• Compatible with Buick Cutlass Supreme, Chevrolet Lumina, Oldsmobile Regal, Pontiac Grand Prix, and Monte Carlo
• Addresses brake fade caused by overheating during heavy braking
• Reduces brake dust buildup for cleaner braking surfaces
• Improves wet weather braking performance by channeling water away
• Helps maintain consistent braking feel and stopping power

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 9.4 mm before installation. Clean the rotor surface to remove any protective coatings or debris. Verify compatibility with your vehicle’s 5-lug, 115 mm bolt circle pattern. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.

Quality Assurance

Dynamite Friction rotors undergo rigorous quality control to meet OEM standards. The rust-resistant zinc silver finish helps prevent corrosion, contributing to longer service life. While no specific warranty information is provided, the product is designed to meet the performance and durability requirements of the listed GM vehicles.
