This product line focuses on delivering consistent braking performance with quality materials and manufacturing processes. The 121.99016 rotor is part of this line, offering a vented design that helps reduce heat buildup during braking, which is essential for maintaining rotor integrity and brake system reliability.

Technical Details and Specifications

This Centric rotor features a vented design with a smooth surface type, which aids in heat dissipation and reduces brake fade under normal driving conditions. The rotor’s nominal thickness is 0.866 inches (22.0 mm), with a discard thickness of 0.787 inches (20.0 mm), indicating when the rotor should be replaced to maintain safe braking performance. The overall height of 1.339 inches (34.0 mm) and an outside diameter of 10.453 inches (265.5 mm) ensure compatibility with specific vehicle models requiring these dimensions. The rotor mounts using a floating disc mounting system with 4 lug holes spaced on a 4.252-inch (108.0 mm) bolt circle diameter, suitable for vehicles with this bolt pattern.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing rotor thickness below manufacturer discard limits
• Improving braking consistency on vehicles experiencing fade
• Resolving noise issues related to uneven rotor surfaces
• Upgrading to a vented rotor for better heat management

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets minimum specifications. Clean the rotor surface to remove any protective coatings or contaminants before mounting. Verify the bolt hole pattern and center hole diameter match the vehicle hub for proper fitment. Since bearings and ABS tone rings are not included, reuse existing components or replace separately as needed. Proper torque specifications should be followed when tightening lug nuts to avoid rotor warping.
