Product Line Details: DFC Brake Rotor - Drilled and Slotted - Black

The DFC Brake Rotor - Drilled and Slotted - Black line from Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and heat dissipation. The black zinc coating on the hat area provides corrosion resistance, extending rotor life. This product line is tailored for solid rotors with directional surfaces, suitable for various GM luxury and performance sedans and coupes.

Technical Description and Specifications

This solid disc brake rotor features a nominal thickness of 11 mm and a discard thickness of 9 mm, ensuring a clear service limit for safety. The rotor’s 281 mm outside diameter and 38.5 mm height fit specific GM vehicles requiring precise dimensions. The drilled and slotted surface design helps reduce brake fade by allowing gases and debris to escape, while the directional pattern optimizes water and dust removal during braking. The zinc black hat finish with rust-resistant coating protects against corrosion, maintaining structural integrity over time. The rotor includes five bolt holes with diameters of 13.1 and 16.3 mm, matching the bolt circle diameters of 115 and 118 mm, ensuring proper fitment on compatible Buick, Cadillac, Oldsmobile, and Pontiac models.

Compatible Vehicles and Common Applications

• Replacement rotor for Buick Allante, LeSabre, Park Avenue
• Suitable for Cadillac DeVille, Eldorado, Seville
• Fits Oldsmobile Regency and Pontiac Bonneville, Aurora, Riviera, Toronado
• Addresses issues such as brake fade, rotor warping, and uneven pad wear
• Improves braking response and heat management under normal and demanding conditions

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it exceeds the discard thickness of 9 mm. Clean the rotor surface to remove any protective coatings or residues before mounting. Verify bolt hole alignment with the vehicle’s hub using the specified bolt circle diameters of 115/118 mm and the five-lug pattern. Proper torque specifications should be followed to avoid rotor distortion. Directional rotors must be installed with the rotation arrow pointing in the correct direction for optimal performance.
