DFC GEOSPEC Coated Rotor Product Line Details

The DFC GEOSPEC Coated Rotor line by Dynamite Friction focuses on corrosion resistance and consistent braking performance. The Geospec silver grey hat finish combined with a rust resistant coating helps protect the rotor from environmental wear, making it suitable for vehicles exposed to moisture and road salts. This product line balances durability with smooth braking surfaces to maintain reliable stopping power over time.

Technical Description and Specifications

This disc brake rotor features a nominal thickness of 11 mm and a discard thickness of 9 mm, indicating when replacement is necessary to maintain safe braking. The rotor’s 305 mm outside diameter and 35.3 mm height are designed to match the brake system specifications of Hyundai Santa Fe and Kia Sorento models. The 5 bolt holes, each 12.6 mm in diameter, align with a 114.3 mm bolt circle diameter, ensuring proper fitment. The rotor’s hat is finished in Geospec silver grey, providing corrosion resistance, while the disc surface is plain and smooth, supporting consistent brake pad contact. The non-directional braking surface allows for flexible installation without concern for rotor orientation.

Compatible Vehicles and Common Applications

• Replacement rotor for Hyundai Santa Fe models requiring 305 mm disc rotors
• Suitable for Kia Sorento vehicles with matching bolt pattern and rotor dimensions
• Addresses issues such as rotor warping, uneven brake pad wear, and rust-related surface degradation
• Helps restore braking performance affected by rotor thickness below discard limits
• Ideal for vehicles experiencing brake noise or vibration due to worn rotors

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the nominal thickness of 11 mm. Clean the hub surface and mounting points to prevent misalignment. The non-directional design allows installation on either side without concern for rotor orientation. Torque the 5 lug bolts to manufacturer specifications to avoid rotor distortion. Inspect brake pads for wear and replace if necessary to optimize braking performance.
