ATE SP00123 Disc Brake Rotor - Front

Overview of ATE SP00123 Disc Brake Rotor

The ATE SP00123 disc brake rotor is engineered for Mercedes-Benz SL400, SL450, and SL550 models. Designed with high-carbon material and a vented construction, this rotor offers reliable braking performance and durability under demanding conditions.

• High-carbon material for enhanced heat dissipation
• Vented full cast construction to reduce brake fade
• Rust resistant coating for extended rotor life
• Nominal thickness of 24.00 mm with discard thickness at 21.4 mm
• Compatible with Mercedes-Benz SL400, SL450, and SL550
• Non-directional smooth surface for consistent braking
• Five stud/lug holes with 15.30 mm diameter and 112.00 mm circle diameter

Technical Specifications and Features

The ATE SP00123 rotor is constructed from high-carbon material, which improves thermal conductivity and reduces the risk of warping during heavy braking. Its vented design allows air to flow between the rotor surfaces, helping to maintain optimal operating temperatures. The full cast construction ensures structural integrity and consistent performance. A rust resistant coating protects the rotor from corrosion, extending its service life. The rotor measures 320.00 mm in outside diameter and 50.50 mm in overall height, with a center hole diameter of 67.00 mm. It features a single mounting bolt hole and five stud/lug holes, making it compatible with the specified Mercedes-Benz SL models. The smooth, non-directional braking surface provides even pad wear and reliable stopping power.

Compatible Vehicles and Applications

• Designed specifically for Mercedes-Benz SL400, SL450, and SL550 models
• Ideal for replacing worn or damaged disc brake rotors on these vehicles
• Suitable for drivers seeking reliable braking performance under normal and demanding conditions
• Addresses issues such as brake rotor warping, uneven pad wear, and reduced braking efficiency

Installation Notes and Tips

When installing the ATE SP00123 disc brake rotor, ensure the rotor thickness is above the discard thickness of 21.4 mm to maintain safe braking performance. Clean the hub surface before mounting to prevent runout and vibration. Use proper torque specifications for the five stud/lug bolts to secure the rotor firmly. Since this rotor does not include bearings or an ABS tone ring, verify compatibility with your vehicle’s existing components. Professional installation is recommended to ensure optimal fit and function.
