• Nominal thickness: 28 mm with discard thickness at 25.4 mm
• Overall diameter: 300 mm, height: 45.4 mm
• Hat finish: Zinc silver coating for corrosion resistance
• Rust resistant coating applied to extend rotor life
• Bolt hole quantity: 5 with 112 mm bolt circle diameter
• Directional brake surface optimized for heat and debris management

Detailed Product Description

This DFC Brake Rotor - Drilled and Slotted - Silver is specifically designed to meet the braking demands of Mercedes-Benz vehicles including the 300SL, 500E, 500SL, SL320, and SL500. 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 drilled and slotted surface pattern aids in expelling gases, dust, and water, contributing to improved brake pad contact and performance under various driving conditions.

Constructed with a plain disc finish and a zinc silver hat finish, this rotor offers enhanced corrosion resistance, which is critical for maintaining structural integrity and appearance over time. The rotor’s 5-bolt hole configuration with a 112 mm bolt circle diameter ensures proper fitment and secure mounting on compatible Mercedes-Benz models. The directional surface design is intended to optimize braking efficiency by channeling heat and debris away from the rotor surface.

Applications and Problem Solving

• Reduces brake fade caused by excessive heat buildup
• Improves braking performance in wet or dusty conditions
• Minimizes rotor warping and extends service life
• Enhances pad bite and reduces brake noise
• Prevents rust and corrosion on rotor surfaces

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented correctly according to the vehicle’s rotation direction. Verify that the bolt hole pattern matches the vehicle’s hub assembly (5 bolts, 112 mm bolt circle diameter). Measure rotor thickness before installation to confirm it meets or exceeds the nominal thickness of 28 mm and is above the discard thickness of 25.4 mm. Proper torque specifications should be followed to avoid rotor distortion.

Quality Assurance

Dynamite Friction’s DFC Brake Rotor line is manufactured to meet or exceed OEM specifications for fit, form, and function. The rust resistant coating and zinc silver hat finish contribute to durability and corrosion protection. While no specific warranty information is provided, the product is designed for reliable performance on Mercedes-Benz 300SL, 500E, 500SL, SL320, and SL500 models when installed and maintained properly.
