• Dimensions: 257 mm outside diameter, 45.7 mm overall height
• Thickness: Nominal thickness 24.5 mm, discard thickness 22.4 mm
• Mounting: 4 bolt holes with 114.3 mm bolt circle diameter and 12.7 mm stud/lug hole diameter
• Directional brake surface optimized for heat and debris management

Detailed Product Description

This Dynamite Friction DFC Brake Rotor - Drilled and Slotted - Silver is designed to meet the braking demands of Hyundai and Mitsubishi vehicles including the Elantra, Sonata, Tiburon, Galant, Lancer, Sigma, Expo, Expo LRV, and Space Star. The rotor features a vented design that improves airflow to reduce heat buildup during braking, which helps maintain consistent stopping power and reduces the risk of brake fade.

The rotor surface is both drilled and slotted, allowing for efficient removal of brake dust, gases, and water, which contributes to improved brake pad contact and performance. The directional pattern of the drilled and slotted surface is engineered to optimize braking efficiency and rotor longevity.

The rotor’s hat is finished in zinc silver, providing corrosion resistance, while the disc surface has a plain finish with an additional rust-resistant coating to extend the rotor’s service life. With a nominal thickness of 24.5 mm and a discard thickness of 22.4 mm, this rotor meets OEM specifications for durability and safety.

Applications and Problem Solving

• Compatible with Hyundai Elantra, Sonata, Tiburon and Mitsubishi Lancer, Galant, Sigma, Expo, Expo LRV, Space Star models
• Addresses brake fade caused by excessive heat during heavy braking
• Reduces brake dust buildup and improves pad contact with drilled and slotted surface
• Prevents rust and corrosion with zinc silver hat finish and rust-resistant coating
• Maintains braking performance with vented rotor design for heat dissipation

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness of 22.4 mm before installation
• Verify bolt hole pattern matches vehicle specifications: 4 bolt holes with 114.3 mm bolt circle diameter
• Use proper torque specifications for lug nuts to avoid rotor warping
• Inspect brake pads and calipers for wear or damage during rotor replacement
